AIDs? I will tell you a condesned summary of AIDs. It is a derivitive from primates and mutated slowly into humankind. However, it may have showed up in gay people at first, but it showed up in straight people. Some people carry the disease but were not infected and were having unprotected sex and spread said disease. That's why it is around. Sex with monkeys and unprotected sex. Nothing to do with the male's ass being clean or not. Also, the first case of AIDs in heterosexuals was with men. Were they raped by a carrier? Maybe, maybe not. Odds are that a girl was a carrier and spread AIDs.
