I have recently been amazed at how common this is in gyms. I have been to a few different gym steam rooms and guys have made their intentions clear. Firstly, I need to say that I have never really done anything with a guy, the closest is a few touches (detailed below), a wank or 2 on a nudist beach (own cocks only) - but I guess I am curious....
The one time, I went in alone, but within 2 minutes, I was joined by 3 other guys - One guy moved in close and started touching my cock, the 2 other guys started touching each other.... then I got scared/ shy and I left. Then a few weeks later at the same gym, the steam room was full (about 10 - 12 guys) when I walked in. The guy next to me started touching my leg and butt, then he pulled his towel half up to hide his cock from most of the room, but still showing me how it was getting hard as he stroked it - I ignored him and then left for the showers as the room was so full. He followed me to the showers, but I closed the privacy screen - he was too hectic for me. About 3 weeks ago, I was in another gym and was in the steam room with 2 other guys. The 1 was clearly not interested, but the 3rd guy seemed to be watching me and looking at my cock. When the other guy left, we moved subtly touched our cocks every so often and then he made a move to touch mine. I let him feel it a little bit and then he made a move to bend his head down to suck and I stopped him. This steam room is very small and you can see inside pretty easily. we chatted abit and played with ourselves a little bit and then I left. It does turn me on though - not sure how far I am willing to go though..... maybe a mutual wank would be nice
