What acts are classified under sexual assault?

The classification of sexual assault includes acts that involve unwanted sexual contact or behavior. Rape is the act of engaging in sexual intercourse without consent, which fits the criteria for sexual assault. Non-consensual sodomy, which refers to anal intercourse or oral sex performed without consent, is also classified under sexual assault because it involves forced sexual acts against the will of an individual.

Both of these acts (rape and non-consensual sodomy) are serious violations of an individual's autonomy and are legally recognized as sexual assault. They share the common element of lack of consent, making them subject to prosecution under sexual assault laws.

Other options, like consensual sex, do not pertain to sexual assault as they involve mutual agreement between partners. Indecent exposure, while inappropriate and often illegal, can be categorized differently, and sexual harassment and stalking deal more with patterns of behavior rather than the physical acts of sexual assault itself. Therefore, the focus on rape and non-consensual sodomy in the correct answer highlights the critical components of sexual assault as defined by law and societal standards.
