I enjoy getting naked in the locker room and the shower at my gym, but it kind of creeps me out when it is obvious people are checkin you out in detail, I don't mind them taking a quick peek but when they sit there and stare or wait for you to get fully naked, it is kind of creepy, specially if you are not attracted to them or they are not naked.
I used to go naked into the sauna and about 80-90% of the other guys were not, they would be in gym clothes, undies, swimsuit or wrapped in a towel, it felt weird being the only naked guy in there and kind of the center of attention, so I started wearing my towel wrapped around my waist. Now if the other guys were all naked in there, it would not have been a problem for me.
I remeber one time, being naked in there and there was another hot guy in there in just his briefs, pretty hot and when I went to shower, he follwed me out and showered accross from me and then went back into the sauna naked, I didn't follow but as he walked by my shower stall he purposley stopped, faced me and gave his dick a wank, I took it as a signal he wanted me to follow him into the sauna to have J/O session but I was to afraid of being caught and chickened out, but it would have been kind of hot.
I was in a steam room once with a towel across my lap when another hot guy came in and his towel begain to expose his privates so I let mine begin to expose mine, we both began growing and he was rubbing his chest and arm's as the sweat was pouring off of both of us, we both began wanking our cocks and eventully both stood up and began wanking each other, he was also pinching my nipples and stuck a finger up my hole when I immediately shot a load into his hand, WOW, i went and showered and got out of there as quickly as I could, but the experience was HOT! This was on a cruise ship
