to the post above me: how did you react? I would have been LIVID mad- and would have demanded him show me what he recorded or snapped- and made him delete it on the spot- and THEN I would have gone to management- as this is basically criminal behavior.
As for the staring issue- I think it's fairly commonplace at my locker room too- but the key I have found is the expectation. Let me explain. For guys that I have never seen there before, or "new guys/strangers", all is fair... and it's like you are two dogs that have to sniff each other's butts... you know, check each other out to see which is the dominant alpha-male. It's in our competitive male nature to do so.
A 'straight' guy won't be overt about it, but if he's self assured and easy going his mannerisms will be anywhere from making a lot of eye contact, offering a nice smile and friendly chat, to just sitting quietly. Depending on his own self confidence of his body, he might wrap up tight like fort knox, or he might sit with his towel very open- leaving nothing to the imagination. It's all fine and good- it's the first interatcion, and it falls into 'behavior around a stranger I'll never see again..."
The guys I see at my health club on a more common basis- (if we are working out on a simillar schedule so you see them frequently) well that's different. I know them because I have seen them before. Some I know as friends or as casual aquaintences. Others I know more about their families or work or whatnot from having or listening to converstations either on the workout floor, sauna or steamroom, etc.
Some guys love the attention- and sit in a way to basically invite you to memorize every inch of their body. Others are more modest. They eyes betray it all: watch a guy's eyes and see what he looks at when he's talking to you, or when you pass by. When you stand up to leave and radjust your towel in the steam room. Use your peripheral vision. If he is aware of his surroundings and is making eye contact with others in the room, he's open to attention.
On the opposite side, I have found that some guys will come into the sauna/steam room, and immediately close their eyes, or put their head down and stare at the floor, or put a second towel over their head to hide themselves completely- because they want to just sit quietly and not be social- just enjoy the heat. Some are basically isolated and acting like they are totally alone in a room full of people- which is also fine, if that's what he wants to do, as a 'defense mechanism' to being surrounded by a bunch of other men wearing only loose towels. I think it's very telling of his self-confidence, but that's just my opinion.
Bottom line is, some guys like to be stared at- they will walk around naked and give you plenty of chances to look. They might shave naked at the sink, or toss their clean towel over their shoulder so that the meat club swings free- after all they've paid their dues and it's a men's lockerroom so they have the right to let it all hang out.
My rule is to know (from prior interactions) who likes to be stared at, who likes to have actual eye-to-eye interactions, who covers themselves as quickly as possible. If I have a comfortable friendship with some guys, I will BLATANTLY give his cock a stare, then look back in his eyes and smile- it's complimentary and he knows it, and welcomes it. Then I'll open up my towel to begin dressing, and give him his opportunity to acknowledge my manhood right back. We are two men who are openly naked in a place where society allows this male bonding- and if it is mutually welcome on both sides, it's affirming behavior and there's nothing wrong with it. I think this aspect of male nature is a bit more understood by men who identify themselves as not 100% straight- at least it doesn't have to be explained.
Taking this rule into perspective, my behavior will also be different around a stranger. I will usually give him a little casual behavioral nudity, to see how he responds. Nothing major- maybe leave my towel a bit more loose than I normally would, or open it to re-tighten it when I stand up, or a quick peek across the corridor as he hangs his towel on the shower hook... but I acknowledge the fact that he is in the room, and that he's another member of my gender with the same sex equipment on display- and see what he chooses to show/look at in the context of being in my presence. It's all about catching the vibe of another guy- and seeing what is comfortable for both of you - as strangers, then as aquaintances- then perhaps as friends- in a place where you both choose to be naked and will frequently run into each other.
Around some dudes in my locker room, I keep my towel quite tightly wrapped around my waist- and it is opened when I am completely INSIDE my shower stall. I've seen them enough times in my locker room to decidedly NOT feel comfortable around them- and I am not made comfortable by their advances or watching how they stare at other guys. Since I can't control their behavior or limit them from using the club that they are also paying to use, I can only be responsible for my own behavior- so I choose to stare at the floor, or ignore them- (no direct eye contact.) This sends them the signal that staring and chatting and other interactions are unwelcomed.
If the locker room trolls (young or old) catch a quick glimpse of my buns as my boxers go up they can take that home to their own bedroom- I can't control that. But I can decide who I give more opportunity to enjoy looking at (and enjoying) my naked body just as I do, and I can be respectful and open to opportunities where the same welcomed behavior will be returned to me. It's the social investment that I put in that goes hand-in-hand with the time I am investing to building my muscles.
OK, discuss.
