Rape in America

The most horrible and traumatic experience that a female can have is that of being raped by a man who is able to overpower her, to make her submit through violence to an act that is supposed to be a loving experience that adult females reserve for their special love partner. It wouldn't be an exaggeration to estimate that at least 10% of men have raped, with most of them never getting prosecuted for those acts. Why are men willing to rape when they can't take "NO" for an answer?
