Male rape (men being the victims of rape) doesn't happen very often, but I have heard that it does happen.

I was just wondering how this would work. Can anyone speak out of experience, or does anyone know of some man who has unfortunately been a victim of rape?

Note: I'm not referring to male-on-male sex in prison, nor am I referring to pederasty (older men having intercourse with young boys).

So how do adult men get raped? Do women gang up on some handsome, hung man and force themselves upon him? Or is it perpetrated mostly by other men??

I'm genuinely interested in understanding this sad phenomenon. Thank you for your serious and sincere responses.
