This is one of my favorite topics for lots of reasons. (By the way, Fratpad.com has astonishing multiple jackoff parties, with good looking college guys. Frankly, I dont know how they manage it; these guys seem straight to me, but, like any red-blooded college guy, they like fooling around with their cocks, and if their buds join in, so much the better.)
Anyway, if I may wax philosophical, it seems from the responses that many, many guys would like to have a JO bud. This surely points to the need of men to have a) intimacy with another man; and b) a chance to do the most natural thing in the world with someone who understands. It makes total sense to me that a straight guy ( tho' frankly, such labels are pretty silly) could do that with a buddy and it wouldn't change his fundamental sexual orientation ( if there is such a thing).
Guys are about cock. period. So, if they can do it with another guy, it's got to hit some chord in a man, since so many guys try it out.
I can't think of anything more healthy and satisfying than jacking off with another guy, or a group of guys. I've been the NY Jacks many times over the years, and invariably I feel like a million dollars afterwards--really affirmed as a man. The other guys do too.
I still jack with guys at my gym in the steam room. It's the best. The whole world would be in better shape if more guys (say, world leaders) simply jacked off together.
