Although I do not really agree or disagree with you (your friend has better arguments than you do), my main concern was with one point - rape. Rape is not sex, my dear. Rape produces trauma because it was not sex. Does sex produce trauma? No. So, yes, we ARE geared for sex. By comparing sex with rape (I thought you would be grown up at 30), you show a need for a psychiatrist yourself. It is SEX that is enjoyable, not RAPE, because it is not a forced act like rape is. Rape is domination and subjugation - therefore, it hurts, just like an act of beating someone in public - the physical scars may heal - the mental ones are difficult - because it happens against one's wishes.
