If you can’t tell they’re doing it, it can’t bother you. Think about it.
I’m flattered if a dog humps my leg.
I’m bothered more by the existence of it than the idea of it. Why? I have my reasons.
What RickJay said. But really, this goes back to whether or not you’re comfortable with a gay man hitting on you.
I’ve had that happen once and basically, in my head I was like “I am so hot!”, but my mouth was trying to stay very neutral because I didn’t want to give this poor guy the wrong idea.
If someone I knew was gay was checking me out, yes definatly. In a gym shower, I would not really care, as said there my point is to shower, soap, shower and out.
It depends on context, if the setting is a club where I am being propositioned, er yes. On a beach, yes. In a gym or in a professional setting; no.
I agree, but IntelSoldier doesn’t. Hence the reason I started this thread.
If I don’t know about it, it can’t possibly bother me.
I’m thinking about a possibly analogous situation with mixed sex changing - it’s pretty likely that there would be a significant level of checking out happening in changing rooms or showers where lots of men and women were simultaneously present - and I reckon the existence of separate changing facilities seems to support the notion that it’s OK to be concerned about it.
So I guess it would be OK to be concerned about same-sex checking out too.
Except I just can’t be bothered. I have no shame, really, and any propriety I appear to exhibit in this matter is almost entirely done for the benefit of others, not myself.
I wouldn’t make a fuss about it, but I would (to be honest) not be as comfortable taking a shower with gay men as I would with hetero men. For whatever reason gay men would try to hit on me when I was in college and several times after that in social situations when I was single. I am pro-gay rights re lifestyle choices, full marriage rights etc. but being viewed and aggressively approached as a sexual object by men was a squirm inducing, and uncomfortable experience.
I have no illusions that my 50 year old hairy chested manliness would be inciting a sword fight, but being naked on front of gay men would not be my preferred scenario if I had a choice.
I can understand why this presumption might cause bother, but in the context of nakedness in a changing room, the mere possibility of interest is enough to warrant separation in the case of men and women. I don’t find all women attractive, but I’ll be in trouble if I saunter into their changing rooms.
I don’t think I would mind. My narcissistic ass would probably be flattered to be checked out.
When I shower, I always take my glasses off so if anyone did check me out, I wouldn’t know about it.
Heh. Interesting choice of words 
For me, no - I used to work out at the SF YMCA so I’m pretty sure that there were a number of gay guys there. I really did not give a hoot in terms of using the locker rooms, showers and saunas. Never experienced anything inappropriate.
Oddly, I have never given it a thought. Having just thought about it, I would not mind.
As long as he can resist the monumental temptation of trying to penetrate my sweet, sweet ass, then no.
I’d worry only that they don’t find me hot. Then, I’d feel fat, pale, and insecure.
Yeah, it’s pretty much exactly the concerns I’d have changing in front of straight women.
I used to go to a gym that was about 90% gay men. I’ve spent a lot of time in the shower with gay men. It doesn’t bother me. In fact, it’s a heck of a compliment if you get hit on in the shower.
Ego strokes aren’t necessarily a bad thing…
It would only bother me if he expressed some kind of sexual interest in me. But given the right circumstances, even that might not bother me. Never had a gay experience, but a blow job is a blow job is a blow job, right? 
o:o
ETA : I should say that I do NOT and WOULD NOT do a communal shower unless I lost a very significant amount of weight, so the odds of me getting a locker room beej are nil.

I think the OP is talking about a communal shower, like at the gym or High School locker room. In a 9-square foot shower, I’d be uncomfortable with ANYONE in there…
Joe
If I minded, I wouldn’t have a Y membership.
