11 Appellant David Waldon Paschal was convicted of four counts of second-degree sexual assault and one count of witness bribery. He was sentenced to ten years’ imprisonment on each of three of the sexual-assault convictions, given ten years’ suspended sentence for the fourth sexual-assault conviction,1 and fined $4000 for the witness-bribery conviction. On appeal, Paschal contends that the circuit court erred in (1) denying his motion for directed verdict on the witness-bribery charge, (2) refusing to admit evidence of bias on the part of the State’s chief witness-bribery-charge witness, (3) failing to sever the witness-bribery charge, (4) finding the second-degree sexual-assault statute constitutional as it was applied to |2him, (5) admitting certain witness testimony during the penalty phase, and (6) rejecting proffered jury instructions. We affirm in part, reverse and remand in part, and reverse and dismiss in part.
I. Sufficiency of the Evidence: Witness Bribery
Paschal contends that the circuit court erred in denying his motion for directed verdict on the charge of witness bribery.2 On appeal, we treat a motion for directed verdict as a challenge to the sufficiency of the evidence. E.g., Smoak v. State, 2011 Ark. 529, 385 S.W.3d 257. In reviewing a challenge to the sufficiency of the evidence, this court determines whether the verdict is supported by substantial evidence, direct or circumstantial. . Id. Substantial evidence is evidence forceful enough to compel a conclusion one way or the other beyond suspicion or conjecture. Id. This court views the evidence in the light most favorable to the verdict, and only evidence supporting the verdict will be considered. Id.
Arkansas Code Annotated section 5-53-108 provides in relevant part that a person commits witness bribery if he or she
(1) Offers, confers, or agrees to confer any benefit upon a witness or a person he or she believes may be called as a witness with the purpose of:
(A) Influencing the testimony of that person;
(B) Inducing that person to avoid legal process summoning that person to testify; or
(C) Inducing that person to absent himself or herself from an official proceeding to | swhich that person has been legally summoned.
Ark.Code Ann. § 5-53-108(a)(l) (Repl. 2005). An “official proceeding” is “a proceeding heard before any legislative, judicial, administrative, or other government agency or official authorized to hear evidence under oath, including any referee, hearing examiner, commissioner, notary, or other person taking testimony or depositions in any such proceeding.” Id. § 5-53-101(4)(A). “Testimony” means “an oral *432or written statement, document, or any other material that is or could be offered by a witness in an official proceeding.” Id. § 5-53-101(5).
Paschal, a high school teacher, had a months-long sexual relationship with eighteen-year-old A.D., a student at Elkins High School, where Paschal taught. Principal Rebecca Martin testified that on May 5, 2010, A.D. and her mother contacted school officials and informed them that A.D. and Paschal had engaged in a sexual relationship. Martin testified that Paschal told her that he knew his sexual relationship with A.D. was illegal and that he was concerned about whether his actions would have an effect on his career and his relationship with his children. Fayetteville Police Department Detective Jonathon Snyder interviewed Paschal that day in the school superintendent’s office, and Paschal admitted that he had engaged in a sexual relationship with A.D. On June 2, 2010, Snyder arrested Paschal, and he was formally charged with four counts of second-degree sexual assault on August 13, 2010.
S.C., a senior at Elkins High School, testified that Paschal was his AP World History teacher during his junior year. S.C. said that A.D. was his friend and a year ahead of him in ^school. S.C. stated that he worked at the local Wal-Mart and that Paschal knew that he worked there. In June 2010, while S.C. was returning to work from a break, Paschal waved at him and walked up to him. According to S.C., Paschal said, “[A.D.] knows that she’s not gonna get any money out of this and if it’s money she wants, I’ll give her a couple of thousand if she’ll drop the case.” S.C. testified that he attempted to contact A.D. through several of her friends, but when he was unable to make contact with her, he told Ms. Taylor, a geometry teacher at the school, what Paschal had told him. S.C. also stated that he told law enforcement officers what Paschal had said. S.C. identified Paschal in the courtroom as the person who had asked him to contact A.D. and offer her money.
Paschal contends that there was no evidence presented to the jury that he had offered A.D. money through S.C. for the purpose of influencing her testimony, inducing her to avoid legal process, or inducing her to absent herself from a legal proceeding to which she had been legally summoned. Paschal states that the conversation with S.C., which occurred in June 2010, was “a month or two” before he was formally charged in August 2010, so there were no legal proceedings at issue. Paschal contends that the evidence illustrates nothing more than his attempt to resolve the matter without all the attention of a trial, much like when prosecutors offer defendants plea offers in an attempt to resolve a pending case. We find no merit in Paschal’s argument.
Paschal was in no position to attempt to “negotiate” with A.D. The State has the authority to bring criminal charges, irrespective of whether the victim wishes to pursue those charges. See, e.g., Clay v. State, 236 Ark. 398, 403 n. 4, 366 S.W.2d 299, 303 n. 4 (1963) (noting that the State is the party in the criminal prosecution, not the victim). According to S.C., Paschal told him to tell A.D. that he would give her money if she would “drop the case” against him. While the decision to bring criminal charges was the State’s and not A.D.’s, A.D.’s allegations formed the basis of the State’s case, and the State needed her cooperation as a witness. When Paschal spoke to S.C., he was aware that criminal charges against him were being investigated by the police, and Paschal was likely aware that A.D. could give a sworn statement for use against him in a criminal prosecution. Finally, even though Paschal’s conversation with S.C. took place *433before formal charges were filed, the statute does not require that a criminal case or any other “official proceeding” actually be pending at the time of the offer. S.C.’s testimony established that Paschal offered to confer a benefit upon A.D. with the purpose of influencing her testimony. We hold that there is substantial evidence to support a conviction for witness bribery. The circuit court did not err in denying Paschal’s motion for directed verdict.
II. Admission of Evidence of Bias
Paschal contends that the circuit court abused its discretion in rejecting his proffered evidence of the bias of S.C. The decision to admit or exclude evidence is within the sound discretion of the circuit court, and we will not reverse a circuit court’s decision regarding the admission of evidence absent a manifest abuse of discretion. E.g., Rollins v. State, 362 Ark. 279, 208 S.W.3d 215 (2005).
At trial, Paschal sought to introduce evidence that S.C.’s father was sued in 2009 in a quiet-title action by J.P. Corporation of Northwest Arkansas, a corporation in which |RPaschal’s father held an interest. The corporation lost the lawsuit, and title to the property was quieted in S.C.’s father on May 11, 2009. During voir dire examination of S.C., S.C. testified that he lived on the property at issue in the lawsuit and that he knew that Paschal’s family was “on the other side of the lawsuit.” Neither S.C. nor Paschal was a party to the lawsuit, and S.C. said that he was not affected by the lawsuit “in any form or fashion.” S.C. testified that the extent of his knowledge of the lawsuit was “just hearing, just second-hand, just hearing it from my parents.” The circuit court concluded that the evidence was not relevant, that it had no probative value, and that it would be prejudicial.
The State contends that the circuit court did not abuse its discretion by refusing the evidence because neither S.C. nor Paschal was a party to the lawsuit, which had ended favorably to S.C.’s father. The State also points out that the lawsuit ended in May 2009, which was nearly two years before S.C.’s testimony at Paschal’s trial and over a year prior to Paschal’s witness-bribery attempt.
As a general rule, all relevant evidence is admissible. Ark. R. Evid. 402 (2011). Relevant evidence is “evidence having a tendency to make the existence of any fact that is of consequence to the determination of the action more or less probable than it would be without the evidence.” Ark. R. Evid. 401. Relevant evidence “may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.” Ark. R. Evid. 403.
“A witness’s credibility is always an issue, subject to attack by any party.” Fowler v. State, 339 Ark. 207, 219, 5 S.W.3d 10, 16 (1999). The scope of cross-examination extends to matters of credibility. See Ark. R. Evid. 611(b). A matter is not collateral if the evidence is relevant to show bias. Fowler, 339 Ark. at 219, 5 S.W.3d at 16. Proof of bias is “almost always relevant because the jury, as finder of fact and weigher of credibility, has historically been entitled to assess all evidence which might bear on the accuracy and truth of a witness’ testimony.” Id., 5 S.W.3d at 16-17 (quoting United States v. Abel, 469 U.S. 45, 52, 105 S.Ct. 465, 83 L.Ed.2d 450 (1984)). “In other words, matters affecting the credibility of a witness are always relevant.” Id., 5 S.W.3d at 17.
*434S.C. was the State’s chief witness for the witness-bribery charge, and Paschal sought to attack S-.C.’s credibility by offering evidence of proof of bias. We disagree with the circuit court’s finding that the evidence was not relevant. The jury should have been allowed to hear this evidence because it might have borne on the accuracy and truth of S.C.’s testimony. The circuit court abused its discretion in refusing to admit evidence of the proof of bias of S.C.
Before leaving this point, we note that, in his brief on appeal, Paschal contends that this situation — where the only evidence of guilt is the testimony of a single witness — should be treated like one in which the testimony of an- accomplice is relied upon by the government and that the denial of cross-examination in such an instance may constitute a violation of the Sixth Amendment right of confrontation. Paschal did not make this argument to the circuit court; therefore, it is not preserved for our review. Our law is well settled that issues raised for the first time on appeal, even constitutional ones, will not be sconsidered on appeal. E.g., Davis v. State, 2009 Ark. 478, 348 S.W.3d 553.
III. Constitutionality of Arkansas Code Annotated section 5-11-125 (a) (6)
Paschal next contends that the circuit court erred in finding that section 5-14-125(a)(6) was constitutional as applied in this case. Statutes are presumed constitutional, and the burden of proving otherwise is on the challenger of the statute. E.g., Jefferson v. State, 372 Ark. 307, 276 S.W.3d 214 (2008). If it is possible to construe a statute as constitutional, we must do so. Id. Because statutes are presumed to be framed in accordance with the Constitution, they should not be held invalid for repugnance thereto unless such conflict is clear and unmistakable. Id.
Arkansas Code Annotated section 5-14-125(a)(6) (Supp.2009), in effect at the time of the crimes charged, provided that “[a] person commits sexual assault in the second degree if the person [i]s a teacher in a public school in a grade kindergarten through twelve (K-12) and engages in sexual contact3 with another person who is [a] student enrolled in the public school and [l]ess than twenty-one (21) years of age.” The record reveals that A.D. was an adult4 when she engaged in a sexual relationship with Paschal, and the State does not dispute Paschal’s contention that the sexual relationship was consensual. Paschal contends that, Inbecause he and A.D. were adults engaged in a consensual sexual relationship, the statute unconstitutionally infringes on a fundamental right. In support of his argument, Paschal relies on the United States Constitution’s protection of the right to privacy, see Lawrence v. Texas, 539 U.S. 558, 123 S.Ct. 2472, 156 L.Ed.2d 508 (2003),5 as well as the Arkansas Constitution’s protection for “all private, consensual, noncommercial acts of sexual intimacy between adults,” see Jeg- *435 ley v. Picado, 349 Ark. 600, 632, 80 S.W.3d 332, 350 (2002). Paschal asserts that, because section 5—14—125(a)(6) infringes on a fundamental right and because the statute is not the least restrictive method available for the promotion of a state interest, it is unconstitutional.
The State responds that there is no fundamental right for a public high school teacher to have sex with an eighteen-year-old high school student enrolled in that public school. In support of its argument, the State cites Talbert v. State, 367 Ark. 262, 239 S.W.3d 504 (2006). In Talbert, the defendant, a minister, challenged the constitutionality of Arkansas Code Annotated section 5-14-126(a)(l)(B) (Repl. 2006), which provides that “[a] person commits sexual assault in the third degree if the person [e]ngages in sexual intercourse or deviate sexual activity with another person who is not the actor’s spouse, and the actor is ... a member of the clergy and is in the position of trust or authority over the victim and uses the position of trust or authority to engage in sexual intercourse or deviate sexual activity.” (Emphasis added.)
Citing Lawrence and Picado, Talbert contended that the statute violated his federal and state constitutional rights to engage in private, consensual sex with other adults. Talbert, 367 Ark. at 269-70, 239 S.W.3d at 511-12. We rejected Talbert’s challenge under the United States Constitution, concluding that, “substantive due process, including his right to engage in private, consensual sex, protects an individual’s liberty interest under the United States Constitution (Lawrence, supra), but Talbert has no liberty interest to engage in sexual activity by using his position of trust and authority.” Id. at 269, 239 S.W.3d at 511. We also rejected Tal-bert’s challenge under the Arkansas Constitution and held that section 5-14-126(a)(1)(B) did “not infringe upon Tal-bert’s fundamental right to have private, consensual sex” because “[t]he conduct criminalized by the statute is the use of trust and authority as a minister over individuals to engage in unwanted sexual activity with them.” Id. at 270, 239 S.W.3d at 512. Further, we noted that the Talbert case was distinguishable from Picado because the “conduct criminalized in [Pica-do ]6 was purely consensual, whereas the conduct criminalized” in Talbert was not. Id., 239 S.W.3d at 512.
Paschal contends that Talbert is distinguishable from the instant case. He asserts that there is a constitutional difference between the coerced sexual conduct that was present in Talbert and the consensual, noncommercial acts of sexual intimacy that are present in his case. We agree. The State misapprehends the issue when it asserts that there is no fundamental right for a public high school teacher to have sex with an eighteen-year-old high school student enrolled in that school. The issue is whether the statute, as applied in this case, |ninfringes on Paschal’s fundamental right to engage in private, consensual, noncommercial acts of sexual intimacy with an adult. We hold that it does.
“[T]he fundamental right to privacy implicit in our law protects all private, consensual, noncommercial acts of sexual intimacy between adults.” Picado, 349 Ark. at 632, 80 S.W.3d at 350. Section 5-14-125(a)(6) criminalizes consensual sexual contact between adults. While it is possible that the General Assembly intended to criminalize a teacher’s use of his or her *436position of trust or authority over an adult student to procure sex, section 5-14-125(a)(6) contains no language evincing such intent. While we might be inclined to assume the General Assembly so intended, we are constrained from making such assumptions. This court strictly construes criminal statutes, resolving any doubts in favor of the accused. E.g., Brown v. State, 375 Ark. 499, 292 S.W.3d 288 (2009). This court cannot, and should not, by construction or intendment, create offenses under statutes that are not in express terms created by the legislature. E.g., Williams v. State, 347 Ark. 728, 67 S.W.3d 548 (2002). Nothing is taken as intended which is not clearly expressed, and this court is without authority to declare an act to come within the criminal laws of the state merely by implication. See, e.g., Heikkila v. State, 352 Ark. 87, 98 S.W.3d 805 (2003).
As applied in this case, section 5-14-125(a)(6) criminalizes consensual sexual conduct between adults and, therefore, we conclude that the statute infringes on Paschal’s | ^fundamental right to privacy.7 A statute that infringes on a fundamental right is subject to strict-scrutiny review, and the statute cannot survive unless “a compelling state interest is advanced by the statute and the statute is the least restrictive method available to carry out [the] state interest.” Picado, 349 Ark. at 632, 80 S.W.3d at 350 (quoting Thompson v. Ark. Social Servs., 282 Ark. 369, 374, 669 S.W.2d 878, 880 (1984)).
The State does not claim a compelling state interest in its brief to this court. Rather, it contends that the Arkansas Constitution clearly contemplates the preservation of a special learning environment for high school students through the age of twenty-one and that the State has a legitimate interest in protecting that environment. Citing article 14, section 1 of the Arkansas Constitution, the State avers that Arkansans aged six through twenty-one have a constitutional right to a public education in a “general, suitable and efficient” public school system, and the State is required to use “all suitable means to secure to the people the | ^advantages and opportunities of education.” The State contends that section 5-14-125(a)(6) preserves the special learning environment because it protects all high school students, regardless of their age, from the sexual advances of teachers who have special authority and control over such students. Further, the State contends that, even if the relationship is consensual, the statute is designed to protect persons, both minors and adults, from people who have power, authority, or control over them on a day-to-day basis. As we understand the argument, the State asserts that it has an interest in protecting adult students from the sexual advances of teachers *437who have power, authority, or control over them.
Assuming that the State has asserted a compelling state interest and assuming that section 5-14-125(a)(6) advances that interest,8 we must determine whether the statute is the least restrictive method available to carry out the State’s interest. We recognized in Picado that “the State has a clear and proper role to protect the public from offensive displays of sexual behavior, to protect people from forcible sexual conduct, and to protect minors from sexual abuse by adults,” 349 Ark. at 637, 80 S.W.3d at 353 (citing Commonwealth v. Bonadio, 490 Pa. 91, 415 A.2d 47 (1980)), and that “criminal statutes, including those proscribing indecent exposure, rape, statutory rape, and the like, are in existence to protect the public from precisely such harms.” Id., 80 S.W.3d at 353. Likewise, we recognize that the State has an interest in protecting adult students from the sexual advances of teachers. But section 5-14-1125(a)(6),14 which criminalizes adult consensual sex, is not the least restrictive method available to carry out the State’s interest. Moreover, the State’s interest is already advanced in section 5-14-126(a)(1)(C) (Supp.2011), which prohibits a mandated reporter9 in a position of trust or authority over a victim from using the position of trust or authority to engage in sexual intercourse or deviate activity.10 Section 5-14-125(a)(6), as applied in this case, infringes on | ,5a fundamental right and is not the least restrictive method available for the promotion of a state interest; therefore, it is unconstitutional. Because we conclude that the statute is unconstitutional on this basis, we need not address the remaining constitutional challenges to the statute. Bayer CropScience LP v. Schafer, 2011 Ark. 518, 385 S.W.3d 822.
*438We feel compelled to point out that the dissenting justices would like to have before them a very different statute than what the General Assembly provided in section 5-14-125(a)(6). Regardless of how we feel about Paschal’s conduct, which could correctly be referred to as reprehensible, we cannot abandon our duty to uphold the rule of law when a case presents distasteful facts.
Paschal’s convictions for sexual assault in the second degree are reversed and dismissed. Finally, because we reverse and dismiss those charges, we need not address Paschal’s remaining arguments on appeal.
Affirmed in part; reversed and remanded in part; reversed and dismissed in part.
