I've had one for the last four years. We met at the gym in the steamroom (no kidding). It was after an early morning work out, and we just started chatting - no weird vibes. This continued for a few months, and then we decided one night to get some drinks. He's married - I'm married. No big deal. I'd noticed his dick (how could I not) and he'd eyed mine, and there was always a repoir between us that felt exciting.
Well, the drinks brought out the honesty, and since then we've been getting together every couple of weeks for some mutual release. It's awesome. Perfect situation, as far as I'm (and he) is concerned.
