This exactly! In 50 years of using locker rooms, showers and the occasional sauna, nothing even remotely sexual has ever happened, ever. It is not the time or place for it, and doing anything sexual would probably get you reported, kicked out of the facility, and potentially arrested.
That's my real world experience in the actual real world that we live in.
I don't mind making contact in them but only for light play where is no chance that someone will become an unexpected witness.
Otherwise, it's just connecting to play later if the person lives close by, or even in the showers if it's possible to do it without making others uncomfortable or being seen.
I don't think the gym is really the place to be doing full on hook-ups either and it's just public/voyeuristic behavior that some are obsessed with.
I once hooked up with a guy a few times who thought it was cute to bare his ass and play on the elevator where I lived and it was a huge turn off for me. We had children and families living there, not to mention the elevators recorded everything. He didn't give a crap though because he didn't live there, I did.
Like I totally get the allure of the encounter of seeing some guy you crushed on, on the gym floor and seeing him later and going through the seductive dance in the steam room or showers, I totally get it, but not everyone else wants to participate and observe. I used to work out a gym where they had to shut down the steam room after too many guys literally would force other patrons to sit through them trying to circle jerk, some of us are literally in there trying to relax and enjoy a steam without all of that. Like go take it to the showers, we worked out in a gym that had very private stalls and nobody really cared if you took your business to the very end of the hall.
