Remembering the first time I did it: Was 18, the summer before going away to college. Had lots of time to go tot he gym,often with my best friend. We had only recently become more open about being nude with each other. I asked him if he dared me to jerk off in the sauna. He did, so stood watch at the sauna door making sure the coast was clear. I did the deed, and had a great time especially at the thought of him half watching me, half watching the door...lol. By the way, did it in the shower there too, not to stray off topic.
