I left my boy intact. I figure his partners will thank me. It didn't seem necessary. My husband was fully on board with it.

My guess is with AIDS that it's the additional contact with a mucous membrane.

Haahaha. I just asked him and he said he hadn't noticed in gym or anything. He honestly did not know what I was talking about until I said, like you or like your dad? He was like Ohhh. Then I told him about snail with a helmet vs. snake with a sweater. He thought that was pretty funny.
