hairy8: Oh it pops alright :D It's a bit like cracking a knuckle or other joint except that it's a duller sound. And once I've popped it I can't pop it again for ages.

It's no surprise that I can pop my cock (hehe) as I can pop/crack just about every other part of my body - back, ankle, elbow, hip, knuckles. I can even crack my sternum in the middle by pulling my shoulders back. None of these sounds cause any pain at all, in fact I feel better after them.

(edit) I was just curious about this penis popping phenomenon so did a google search. Found an article in the "alt.gothic" newsgroup entitled "The mechanics of penis popping" If anyone's interested, the article can be found in google's usenet archive
