I'm sure it is happening more than I realize. Unfortunately, trauma and predation are par for the course in our culture, although the research I've seen says that girls and women who do that are most likely to have had it done to them first. Perhaps that's true of some boys and men as well - but aggression, domination and control of others are traditional masculine gender norms. It's literally the way boys are taught to be men.

Psychologist Michael Thompson has pointed out that silence in the face of cruelty or sexism is how boys become men. Charis Denison, a youth advocate and sex educator in the Bay Area, put it another way: “At one time or another, every young man will get a letter of admission to ‘dick school.’ The question is, will he drop out, graduate, or go for an advanced degree?”
