Well, I’ve watched mine crawl around on occasion, of course utterly fascinated. I knew it probably had something to do with temperature regulation but it wasn’t something I talked about. Until I met Mrs. O. Her favorite line on this subject is “Oh, the boys are tryin’ to escape again.” She likes to blow on 'em and cool them down, then make sound effects as she watches 'em crawl up into my abdominal cavity. One interesting side effect of inguinal hernia surgery in '92 - my leftie will literally disappear inside after an orgasm. Always freaks me out; I’m afraid it won’t come back out again afterwards! ---

What you guys need is one of those cool testical isolators. They are big blue cloth thingies, with a nice little oval shaped hole in the middle. You cover everything and then pull just the sac thru the hole. Wierd looking, but effective! 😃 [Previous page](https://boards.straightdope.com/t/male-anatomy-question/31864.md?page=2)
