This has been going on for thousands of years. That is probably why there are a few passages in the Bible condemning men who lie with men as if they were women; it was basically a condemnation of male on male rape. The people who lived when those passages were written would have understood that. The purpose of that sort of rape is to disrespect and humiliate defeated enemies.
If you do some google searches, you will find articles about African men who have been raped. One reason they are reluctant to report it is that if they do, they are rejected and humiliated by other villagers.
Look what happened when women were being raped when Yugoslavia broke up. I haven't seen any reports of men being raped there, but women who were raped were rejected by their families. The "blame the victim" attitude never ceases to amaze me, especially when it is held by people who claim to be Christians. I wish that there were some way to subject those with a "blame the victim" attitude to the same treatment for which they blame victims, i.e., if they blame men for having been raped, then rape the blamers; they deserve it.
