I've been there several times myself...and I do agree that the best approach is honesty in this situation. I don't know how well you really know this guy and the reason I asked because in each of my situations, I waited until each of these guys were comfortable being in my presence because many times, if a guy like being in your company, it will be easier to tell them. Again, I can't tell you if your situation will have the same effects as mine did, but I do know when I felt that I was developing a friendship with these guys although I found myself attracted to them, when I told them about my sexual orientation, each one gave me much more respect because I was willing to share that with them and it made them feel special that I did that...That's all I'm gonna share with you right now...lol
