Excluding bathhouse type gyms, probably my best legitimate gym adventures were at the 24-hour fitness on Camelback in Phoenix, a notorious gay cruising gym. I had two memorable experiences there.
Two rows of showers that faced each other with curtains. Everyone always left their curtain open a crack so people could see in and check you out. I went in there one night after working out and there was this amazing young hispanic twink standing in the end shower. Maybe 5'-7", skinny, long black hair, and really nice meaty cock (even though it was completely soft). I took the shower opposite him and left my curtain completely open. I did my usual washup and couldn't help notice that he just stared at me openly the whole time. When I was done I stared back at him and started soaping up my cock. He was so hot and I was so horny that, for the first time, I got fully hard - a first for a regular gym shower for me. He made no motions and didn't touch his cock at all, which now looked like a semi-chub. But he didn't try to hide his staring at all. His gaze would shift between my eyes and my cock, mostly my cock. I was close to cumming but held off, edging myself, shifting poses and holding my cock in different ways to show it off to him. This went on for 10 minutes at least but then another guy came into the showers so I shut down the show and left. Didn't see him in the lockerroom afterwords.
The other good time was with this very sexy 20-something kid, again hispanic, who had a very firm, athletic build. After my shower I opened the curtain to grab my towel and he was in the opposite shower, curtain open, with a full hard on. I nodded to him and dried myself off, staring at his beautiful cock the whole time. He stepped out the same time as me and said, "sauna?". So on the way back to the lockers I ducted into the dry sauna which was fortunately empty. He followed me in and made immediate moves. He clearly wanted to suck my cock which was 3/4 hard by now. He sat on a bench and I stood before him. I was REALLY nervous we'd get caught, even though I'd heard it was really common for this to go on and no one really cared. Most guys would gladly watch and stand guard. But we were the only ones. He sucked me for only a minute or so before I got too nervous and wrapped myself up again. He asked if I wanted to meet at his car. So after we dressed I followed him to the covered parking to his car, a really nice new cadillac. I sat in the passenger seat and he said he wanted me to cum in his mouth. I pulled my shorts and he leaned over and gave me an incredible blow job. I stopped him at one point and said I wanted to suck him. He pulled out his really nice, dark skinned cock and I went down on him. It was a great size for sucking - not too thick, and just the right length for me. After a minute we switched again and he sucked me off till I came in his mouth, which he swallowed. After cumming I lost the urge to suck him off so I said thanks and left. Never saw him again. I always kick myself, I was horned up again before I was halfway home, wishing I'd let him cum in my mouth.
Here's my cock:
