I don’t know what “genetic strategy” means, but the real reason for rape is control. Rape has nothing to do with sex. In fact, some rapists use objects (Jon Benet Ramsey).
My cousin was raped our freshman year of college. She was yelled at by the nurse at the hospital for refusing to take the morning after pill.
Utter nonsense.
If it weren't about sex, there wouldn't be a baby.
