Someone on #everything once told me he was raped in high school. Basically he was forced into sex by a girl he didn't want to have sex with. Women rape too, they just don't get in trouble for it.
I'd also like to take a minute to talk about male prostitutes and rape. I have friends who used to be male prostitutes, at the age of 14. They'd go down to the Castro District in San Francisco, and wait to be picked up. They'd then have sex with the person for a pre-determined amount of money or food.
As far as rape goes, I know two people who (on separate occasions) were raped. One was at a gay night club where he was given roofies in his drink. They took him home, each took turns, and then left him naked in a dumpster.
The next boy was 16. He was at a train station, and was jumped by three older men. The all took turns raping him. He spent 3 months total in the hospital. They kicked his testicles until they were so swollen one had to be removed. Surgery for internal bleeding had to be performed twice. He's also HIV+ because of the event.
