IIRC, Muhammad taught his followers that it was okay to treat captured men "as eunichs" (forcibly sodomize them) as long as the captured men weren't Muslim and as long as the Muslim was aggressive not passive (I took that to mean the Muslim shouldn't be on the receiving end of sodomy). This was when Muhammad and his merry men were out terrorizing and the men asked Muhammad if they could use the captured men to satisfy their urges since it had been a while since they had been back home with their wives.
Almost a repeat of what Muhammad's terrorists had asked of him at an earlier time, except it was permission to rape female captives.
