I do feel like straight guys (especially the younger ones) these days are super nervous about being naked in front of gay guys. The gym I go to is about 80% straight and I see a definite difference in how they act in front of the gays guys (myself included) vs. their hetero counterparts. The gym isn't particularly cruisy and the gay guys are mostly very low key and there to work out... not hit on anyone. Most of us aren't the least bit interested in them, or trying to check them out, even if some of us do "read" gay. But, you'd think we were constantly ogling them, or worse, given the lengths they go to in order to conceal themselves, avoid eye contact, or suggest in any way they might be remotely gay-friendly. It's kind of annoying (it's 2023 after all). But it is what it is.
