Long story short, after chickening out more times than I can count I put an ad on Craigslist and have arranged a night over the weekend with another bi guy.
Seriously nervous but so turned on about it and he seems like a cool guy
It won't be my first experimentation as I've received/given drunken handjobs with a similarly 'straight' friend but I didn't go looking for that. We just came home after a night out, watched some porn and he grabbed my cock. Kinda had to return the favour I suppose!
Anyway this is a bit of a 'thanks for the info' kind of post, but I don't have anyone else to talk to about it. I don't want to have to label myself as anything to anyone.
