Most (about 80%) of all sexual assaults are committed by someone known to the victim (US Department of Justice).
Sexual assault can happen to anyone, including men. The vast majority of victims, however, are female.
Men make up 7 to 9% percent of all adult rape victims, while boys account for about 25% of child victims (US Department of Justice).
Men who molest boys are not necessarily homosexuals. Pedophiles prefer children as sexual partners and may be attracted to one gender or the other, or their preference may be based on age rather than gender. Male pedophiles often prey on boys simply because boys are more available to them.
Rapists choose their victims based on opportunity, accessibility, and the victim's vulnerability.
Rape is a crime of violence, control, and domination. Sex is the weapon.
Rapists can't be picked out of a crowd by their looks, occupation, ethnic group, or social background.
Every rape is a potential murder. Fighting back might keep a victim from being raped, but on the other hand, fighting back might get the victim killed. Whatever the victim does to survive is OK.
