If a woman has had too much to drink and has passed out, or is not in control of herself, having sex with her is rape. The fact that you were intoxicated is not a legal defense to rape. You are responsible for your actions, whether you are sober or not. Be aware that a man's size and physical presence can be intimidating to a woman. Many victims report that the fear they felt based on a man's size and presence was the reason they did not fight back or struggle.
Men can be victims of rape and have the same rights to counseling and legal action as women do.
