What offense is committed when a man forcibly inserts his penis into a woman's anus?

The correct answer is that this act constitutes Aggravated Sexual Assault. This offense is characterized by the use of force or the threat of force to engage in sexual intercourse against a person's will, particularly in a manner that causes bodily injury or places the victim in fear of serious bodily injury or death.

In the context of this scenario, the act described goes beyond mere sexual assault since it involves a violent action (forcibly inserting the penis into the anus) that can cause significant physical and emotional harm to the victim. Therefore, the circumstances (such as the use of force) elevate the crime to aggravated sexual assault, which carries more severe penalties due to the heightened risk of harm.

Other choices do not accurately represent the severity and specifics of the offense committed in this situation. Sexual Assault generally refers to non-consensual sexual contact or activity, whereas Indecent Assault usually pertains to less severe actions that do not involve forcible penetration. Criminal Sexual Conduct is a broader term that varies by jurisdiction, but in many cases, it encompasses acts that could involve sexual assault or aggravated assault depending on the circumstances. However, the act in question explicitly aligns with the more serious charge of Aggravated Sexual Assault, reflecting the nature of the forced act described.
