Sauna/ steam room/ shower j/o

I have read multiple stories on here that guys just causally jerk off at the gym in these places with someone else, but how?! How does it start?! Who initiate it?! I get confused with you guys stories because you guys leave that pivtol part out. I wonder if these stories are true. If you have jerked off with someone else or multiple people at these places, what was the beginning process? I'm trying to find my jerk off buddy! Also, I feel the area you live in plays a part into, so share that too

Thanks
Most times I’ve experienced this have been with guys I already knew from elsewhere so we started out with an understanding. However, twice I jerked off with strangers in a sauna and it was just by pure “stroke” of luck. We caught each other looking and it didn’t take long to send the necessary signals. Decreasingly subtle glances and movements eventually exposing our boners and going at it. Wish it was a more common occurrence but no such luck.
