On discretionary review before this Court, the State first argues that it met its burden of proof at trial as to all essential elements of the crime of second-degree sexual offense. The Court of Appeals concluded that no substantial evidence was introduced at trial to support a reasonable finding that the defendant in the present case used force in the commission of the offense charged. For that reason, the Court of Appeals concluded that the defendant was entitled to his liberty and reversed the trial court’s judgment without reaching the defendant’s remaining assignments of error. For reasons which follow, we conclude that the Court of Appeals erred in its conclusion and holding. Therefore, the decision of the Court of Appeals must be reversed, and the judgment of the trial court must be reinstated.
The evidence introduced at trial tended to show that the victim, an adult female, was employed as a registered nurse at Pitt County Memorial Hospital. She had long suffered from cystic fibrosis, *266an hereditary pulmonary disease. She became seriously ill and was hospitalized as a patient at Pitt County Memorial Hospital on 20 December 1989. A course of treatment was commenced, including the intravenous administration of antibiotics. During 21 December 1989, the victim was coughing up blood and was nauseated. By the evening of 22 December 1989, she was feeling better and was able to watch television. About 11:30 p.m., she turned the television off and went to sleep. A nightlight was on in her room. The bathroom door was cracked open, and the light in the bathroom was left on.
At approximately 1:10 a.m., on 23 December 1989, the victim aroused from her sleep sufficiently to become aware that someone was feeling her identification bracelet and feeling the tubing being used to administer antibiotics to her intravenously. The victim assumed it was her nurse and did not open her eyes. The person then pulled down the bedclothing and began feeling the victim’s abdomen. The victim assumed her nurse was assessing her condition by conducting abdominal palpitation, which is a routine procedure for assessing the condition of patients who have experienced nausea. The person then pulled up the victim’s nightgown and pulled her panties aside. Immediately thereafter, the victim opened her eyes for the first time when the person placed his fingers in her pubic hair. The victim saw the defendant standing over her. The defendant then pushed his finger into the victim’s vagina. When she moved, he began to walk away from the bed and toward the door. At that point the victim could tell that he was not dressed as a nurse. She sat up and said, “Sir, may I help you?” The defendant turned as he left the room and said, “No, ma’m, everything’s okay, just go back to sleep.”
When the man left her room, the victim turned off the solution of antibiotics which was being administered to her intravenously, picked up the pole on which the antibiotics were hanging, and went into the hall outside her room. She saw the defendant walking down the hall, and she called for someone to stop him. The victim told her nurse, Mrs. Horsely, what had happened and described her assailant. Nurse Horsely recognized that the description the victim gave of her assailant fit the man Horsely had seen in the hallway a few moments before. Nurse Horsely, with the assistance of a police officer, located the defendant in the front lobby of the hospital. Nurse Horsely recognized him as the man she had seen coming from the direction of the victim’s room at about the *267time the victim had been assaulted. Shortly thereafter, the victim identified the defendant as the man who had assaulted her in her hospital room.
Under N.C.G.S. § 14-27.5(a):
A person is guilty of a sexual offense in the second degree if the person engages in a sexual act with another person:
(1) By force and against the will of the other person; or
(2) Who is mentally defective, mentally incapacitated, or physically helpless, and the person performing the act knows or should reasonably know that the other person is mentally defective, mentally incapacitated, or physically helpless.
N.C.G.S. § 14-27.5(a) (1986). We neither consider nor decide whether the evidence in this case would support a reasonable finding that the victim was “physically helpless” as that term is used in the statute, N.C.G.S. § 14-27.5(a)(2), since the charge against the defendant was not submitted to the jury on that theory. Instead, the charge against the defendant was submitted to the jury on the theory that the defendant engaged in a sexual act with the victim by force and against her will in violation of N.C.G.S. § 14-27.5(a)(l), and the jury returned its guilty verdict based on that theory. Our inquiry concerning this issue on appeal, then, is limited to the question of whether there was substantial evidence to support a reasonable finding that the defendant used the force required to sustain his conviction under N.C.G.S. § 14-27.5(a)(l).
The phrase “[b]y force and against the will of the other person” as used in N.C.G.S. § 14-27.5(a)(l) has the same meaning as it did at common law when it was used to describe an element of rape. State v. Locklear, 304 N.C. 534, 539, 284 S.E.2d 500, 503 (1981). That element is present if the defendant uses force sufficient to overcome any resistance the victim might make. See, e.g., State v. Etheridge, 319 N.C. 34, 46, 352 S.E.2d 673, 681 (1987) (quoting State v. Alston, 310 N.C. 399, 409, 312 S.E.2d 470, 476 (1984)); State v. Jones, 304 N.C. 323, 330, 283 S.E.2d 483, 487 (1981); State v. Bailey, 36 N.C. App. 728, 732, 245 S.E.2d 97, 100 (1978). “The requisite force may be established either by actual, physical force or by constructive force in the form of fear, fright, or coercion.” Etheridge, 319 N.C. at 45, 352 S.E.2d at 680. Constructive force may be shown by evidence of threats or other actions of the defend*268ant which compel the victim’s submission. Id. Such threats “need not be explicit so long as the totality of circumstances allows a reasonable inference that such compulsion was the unspoken purpose of the threat.” Id. The defendant argues that no evidence of either actual physical force or constructive force was introduced at trial in the present case. In support of this argument, he relies strongly inter alia upon reasoning applied in State v. Alston, 310 N.C. 399, 312 S.E.2d 470 (1984). The defendant’s reliance is misplaced.
Alston arose upon evidence so peculiar that the decision in that case may well be sui generis. The alleged victim in Alston had engaged in a consensual sexual relationship with the defendant for six months prior to the rape alleged in that case. Uncontroverted and uncontested testimony by the alleged victim herself showed that when they had sexual intercourse during that relationship, she would remain entirely motionless while the defendant undressed her and had intercourse with her. On the day of the alleged rape, the defendant waited outside the school which the woman attended. He grabbed her arm and told her she was going with him. As they walked away, he threatened to “fix” her face. The two then walked around the neighborhood and discussed their relationship. Eventually, the alleged victim followed the defendant to the home of a friend. There, as she testified was customary and usual conduct between them, the defendant began to undress her and told her to lie on the bed. Then, in accord with what she also described as usual and ordinary conduct between them, the defendant pushed her legs apart and had intercourse with her while she offered no resistance and remained motionless. She then left and went home. She waited some time but, after telling her mother what had happened, contacted law enforcement authorities who charged the defendant Alston with rape. Uncontested and uncontroverted testimony by the alleged victim in Alston also indicated that after the defendant had been charged with rape, he came by her apartment to see her.
Brown said she sat and looked at him, and he began kissing her. She pulled away and he picked her up and carried her to the bedroom. He performed oral sex on her and she testified that she did not try to fight him off because she found she enjoyed it. The two stayed together until morning and had sexual intercourse several times that night. Brown did not *269disclose the incident to the police immediately because she said she was embarrassed.
Alston, 310 N.C. at 403, 312 S.E.2d at 473.
Based upon the unique uncontroverted facts of Alston, we concluded that the victim’s testimony that she had acquiesced due to some “general fear” of the defendant due to his past tendencies for violence was not evidence that the defendant had used force or threats to overcome the will of the victim to resist the particular sexual intercourse alleged to have been rape-, we also concluded that absent such evidence, the defendant’s conviction could not stand. Id. at 409, 312 S.E.2d at 476. In more recent cases, we have clearly stated that the “general fear” reasoning of Alston should be applied only to situations like the peculiar factual situation presented in that case. Etheridge, 319 N.C. at 47, 352 S.E.2d at 681; State v. Strickland, 318 N.C. 653, 656, 351 S.E.2d 281, 283 (1987). This clearly is not such a case.
Based on substantial evidence introduced at trial, the jury could reasonably find that the defendant in the present case used actual physical force sufficient to overcome any resistance the particular victim he had chosen might have offered. In reaching our conclusion in this regard, we neither consider nor decide whether the actual physical force which will establish the force element of a sexual offense may be shown simply through evidence of the force inherent in the sexual act at issue. But see State v. Raines, 72 N.C. App. 300, 324 S.E.2d 279 (1985) (declining to adopt such a definition of “force” under N.C.G.S. § 14-27.5(a)(l)). We expressly defer any decision on that question until we are presented with a case which requires its resolution. Here, the evidence tended to show the defendant used actual physical force surpassing that inherent in the sexual act he committed upon the victim.
When reviewing the sufficiency of the evidence to support a defendant’s conviction, as when reviewing a defendant’s motion to dismiss for a lack of evidence,- all evidence admitted, whether competent or incompetent, must be considered in the light most favorable to the State. See generally State v. Scott, 323 N.C. 350, 372 S.E.2d 572 (1988). The State is entitled to every reasonable inference. Evidence favorable to the State must be deemed to be true, and any inconsistencies or contradictions therein must be disregarded. Id. The question for the Court is whether there is substantial evidence of each essential element of the crime charged *270and whether the defendant was the perpetrator of the crime. Substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.
[1] The issue in dispute in this case is whether there was sufficient evidence of the element of force to support the defendant’s conviction for second-degree sexual offense under N.C.G.S. § 14-27.5(a)(l). Taken in the light most favorable to the State, the evidence tended to show that the defendant and his victim were absolute strangers to each other. Nevertheless, the defendant entered the hospital in which the victim was a patient. With no lawful basis to do so, the defendant pushed open the door of the victim’s hospital room in the middle of the night and entered unbidden into her darkened room. There he found the female victim suffering from cystic fibrosis and attached to the tubing through which she was being administered antibiotics intravenously. Her eyes were closed, and the defendant had no reason to believe she was conscious. Finding his victim in this condition, the defendant pulled back the bedclothes on the victim’s bed, pulled up her gown, pulled down her panties, and put his fingers into her pubic hair. She opened her eyes, and he immediately pushed his finger into her vagina, thereby committing the sexual act necessary to establish a sexual offense. When his victim moved slightly, the defendant went immediately to the door of the darkened hospital room, which he had closed after entering the room, and made his escape. Such conduct by a defendant might not amount to force sufficient to overcome any resistance of the victim or the will of the victim to resist if, as in Alston, the defendant’s actions were directed toward a woman who, over a long period of time before and after the alleged criminal act, voluntarily permitted the defendant to regularly engage in identical conduct. But see generally Susan Estrich, Rape, 95 Yale L.J. 1087 (1986) (a thoughtful article, described by the author as “a study of rape law as an illustration of sexism in the criminal law,” which makes strong arguments to the effect that the law should treat such conduct as “force” even on those facts or should abandon the element of force). Here, however, where the evidence was that the defendant entered a hospital in the middle of the night and went into the room of a patient whom he had never seen before, a jury could reasonably find that his actions in pulling back the bedclothing, pulling up the victim’s gown, and pulling her panties aside amounted to actual physical “force” as that term is to be applied in sexual offense cases.
*271Pursuant to our order allowing the defendant’s motion to bring forward additional issues, the defendant has briefed and argued other issues before this Court. We turn now to an examination of those issues.
[2] The defendant argues that the trial court erroneously instructed the jury on the element of force required for second-degree sexual offense under N.C.G.S. § 14-27.5(a)(l). Specifically, the defendant complains that the trial court erred in instructing the jury as follows:
Secondly, the State must prove that the defendant used or threatened to use force sufficient to overcome any resistance the victim might make. Force or threat of force may be either actual or constructive. Thus, the force necessary to satisfy this element need not be actual physical force; it can be constructive force. Fear, fright or coercion may take the place of actual force. A threat which under all of the circumstances then existing would reasonably induce a fear of serious bodily harm in the mind of a person of ordinary firmness and did in fact create such a fear in the mind of the victim would constitute the requisite constructive force required by law.
The defendant objected to this part of the trial court’s instructions. He argues such instructions could have led the jury to convict if the jury merely found that the victim suffered from fear, fright or coercion, but did not. find that such fear, fright or coercion was induced by the defendant’s actions. The trial court expressly instructed, however, that the jury could convict the defendant on the theory of a threat of force sufficient to overcome the victim’s will, if the threat he made “under all of the circumstances then existing would reasonably induce a fear of serious bodily harm in the mind of a person of ordinary firmness and did in fact create such a fear in the mind of the victim.” (Emphasis added.) This argument is without merit.
[3] The defendant also argues that an instruction permitting the jury to convict the defendant upon the theory of a threatened use of force was error in the present case because it was unsupported by any evidence that the defendant’s actions in fact created a fear in the mind of the victim prior to the defendant committing the sexual offense. Again, we do not agree.
Substantial evidence in the present case tended to show that the victim opened her eyes and saw the defendant after he had *272placed his hand on her pubic hair, but before he had actually penetrated her vagina with his finger. In this regard, the victim testified as follows:
Q. Now, from the time you opened your eyes until this ultimate act occurred, how many — how long would you say that took?
A. A matter of seconds. It seemed like hours.
Q. What were you thinking as you were lying there?
A. I was in shock. I didn’t know what to do. I was afraid that he was going to hurt me or continue what he had started. I didn’t know what to do.
Q. What happened then?
A. I moved my leg. I was still lying down. He walked away from the bed, started towards the door.
Q. What was your emotional state at that time?
A. I was in shock.
Q. Were you frightened?
[A.] Very much so.
Q. What were you frightened about?
A. I didn’t know who it was, why they were there or what they were going to do next. I didn’t know if he would try to kill me.
(Emphasis added.) From this testimony, the jury reasonably could have found that the victim, as a result of the defendant’s presence in her room and his actions toward her, was afraid that the defendant would hurt her, and “didn’t know what to do.” Her fear caused her to do nothing and enabled the defendant to push his finger into her vagina. Further, a jury reasonably could have concluded that, under the circumstances, the defendant’s presence and actions amounted to a threat of force sufficient to overcome any resistance of the victim.
[4] The defendant next argues that the trial court erred by declining the defendant’s request to give the pattern jury instruction concerning identification of the defendant as the perpetrator of *273the crime charged. As any error here is not alleged to have arisen under the Constitution of the United States, the burden is on the defendant to show that, had the error not been committed, a different result would have been reached at trial. N.C.G.S. § 15A-1443(a) (1988). Assuming arguendo that the trial court erred in failing to give the instruction requested, we conclude that the defendant has failed to show that the error was prejudicial.
In the present case, the victim’s identification of the defendant as the perpetrator of the crime charged was absolutely unequivocal at all times from the point of his apprehension moments after the crime was committed through the trial of this case. Nurse Horsely’s identification of him as the man in the hall at about the time of the crime (approximately 1:10 a.m.) was also unequivocal.
Further, the instructions given by the trial court made it clear to the jury that before the jury could convict, the jury must be satisfied beyond a reasonable doubt that this defendant committed the crime charged. As the trial court defined each element of the crime, it expressly stated that the jury must find that “the defendant” had engaged in conduct sufficient to establish that element. The trial court then further instructed the jury:
So I charge you that if you find from the evidence and beyond a reasonable doubt that on or about . . . December 22, 1989, the defendant John Brown engaged in a sexual act with the victim . . . , and that he did so [by means that established the elements of the crime charged] ... , it will be your duty to return a verdict of guilty of second-degree sexual offense as charged.
(Emphasis added.) In light of the victim’s unequivocal identification of the defendant and the instructions given by the trial court in the present case, we are convinced that the jury had a clear understanding that it must be satisfied beyond a reasonable doubt that this defendant committed the crime charged in order to return a verdict of guilty. See State v. Shaw, 322 N.C. 797, 804-05, 370 S.E.2d 546, 550-51 (1988). Therefore, the defendant has failed to carry his burden of showing prejudice.
[5] Finally, the defendant argues that the trial court erred by failing to instruct the jury on the lesser included offense of attempted second-degree sexual offense and by failing to have the jury consider returning a verdict finding him guilty of that lesser in-*274eluded offense. Having reviewed the evidence introduced at trial, we are convinced that all of the evidence tended to show that, if the defendant committed any crime at all, he committed the crime of second-degree sexual offense for which he was tried. In such situations, the trial court must refuse to charge on lesser included offenses. E.g., State v. Bagley, 321 N.C. 201, 210, 362 S.E.2d 244, 249-50 (1987), cert. denied, 485 U.S. 1036, 99 L. Ed. 2d 912 (1988).
For the foregoing reasons, we conclude that the State introduced substantial evidence of the defendant’s use of force —both actual and constructive — and that the defendant’s trial was otherwise free of prejudicial error. Accordingly, we reverse the unpublished decision of the Court of Appeals and remand this case to the Court of Appeals for its further remand to the Superior Court, Pitt County, for reinstatement of the judgment of the trial court.
Reversed and remanded.
