Colubra over on LiveJournal posted this priceless quote. Every time I read it I just go buh. So I decided to relay it here for all you non-LJ folks (people on LJ can ignore this if they've read it).

It's a proven fact that a single anal sex experience causes one to be homosexual. The hormones released by a sexual situation involving the anus being broached, are the same hormones found in large quantities in effeminate homosexual males. For example, when I was much younger I knew a young man who was for all intents and purposes, heterosexual. He was mugged, and involved in a rape situation involving a tent peg. This one event was enough to have him start on a road that eventually led to him becoming effeminate and gay. --Anne McCaffrey, author
