Just about havin, fun that's all.A lot of guys do this... Contrary to what anyone else says! If you are friends before, then nothing changes, as long as you set parameters on the situation before jerking together. Some people think is is "gay", but that is a matter of opinion. Just be careful bringing it up to your friends. Bring it up casually first, and gauge their reaction. Then either procede by asking, or terminate the idea due to their objection. Beer and having a porn going to help gauge the situation, from my own experiences...
This one's for str8 guys who have or have had regular j/o buddies. How has jacking with your friend changed you relationship? Is it better now, worse, no different? Please don't get on on here saying if you do it you're not really straight, try to stay on topic please.
So far it hasn't but I don't do it as frequently as I did when I was in high school. I think the most important aspect of this is trusting the other guy. If you have that trust, then jerking off together is just sharing another aspect of your friendship. If it becomes more intimate, then it's something you might want to discuss with each other and find out where things are going.
