You should come visit my gym in that case, they have absolutely no shame here and aren't closeted for the most part. Just a few weeks ago I was showering after a training session and when I got the shampoo out of my eyes I noticed some random guy was peeking through and jerking off while watching me shower. When he saw I noticed him he pulled his pants back up and ran. I yelled out after him "your welcome" hahaha. Kind of grossed me out since it happened at my cousin's gym as well and its creepy when someone is watching you like that uninvited and you not even knowing.
When I go to NYC to visit friends or just BS in the city, you can go to certain neighborhoods and the guys will start hitting on you like you wouldn't believe. I was with an ex-gf years ago and a random gay couple interrupted us and asked if I'd be willing to join a 3sum. First time it had happened so I was taken back by the bluntness but my ex started to get passed since they kept getting in our way and bothering us. They eventually offered her to join in but we politely declined. Few blocks later, same thing except it was one guy alone. Later that same evening, My ex goes into a store to buy some water and when she comes back out another guy is trying to hit on me lol. Moral of the story: if you don't want closeted bi/gay guys come out to NYC.
Lol I used to live in San Francisco, I know all too well how gay and bi men operate at the gym. Back there, there is a sauna where it is literally a 24/7 orgy that goes on, people come and people go to keep it busy. The only time it is stopped is from 3-4 when they clean the place (thank god!). But, I personally find that behavior dispicable. People here even do it where they try to sneak a peek at guys, and quite frankly if you want to see dick go to the internet.
I prefer guys who are more mellow about the whole thing. Being gay doesnt mean you have to be a slut, you can have a life that is a little more focused on things other than sex. But yes, NYC has plenty of open gay men haha.
