Yeah. Relax. I can't even imagine the conversation with a friend about jacking together, and I'd probably be all scarred if I tried it, but I grew up pretty Catholic, so just hooking up with girls was anxiety inducing enough.
I'd say if you enjoyed it, whatever. Letting your friend jerk you off is definitely taking it to a different level, but if it was fun for you and you get the urge, in a perfect world you should be able to do what you want as long as its safe and everybody is into it.
I would not, however, tell too many of your other guy friends about it.
