I don't joke like that very often, but then I'm a fairly private person. Even the people that know me well say it took a while to really get to know me. And outside this forum, I can count on one hand the number of non-lovers that I've discussed my dick size with. I don't really care about the dick size of my friends or relatives, so I figure they don't need to know mine.

On the other hand, I have heard the kind of talk you're referring to. My belief is that men discuss it in more of a boast/joke/exaggerate, but not quite as intimate. Some of the friends of my exes have known things I wouldn't tell anyone.
