Yep just like you said it they feel different one can be tighter another can be loose one can mold nicely around your dick others are easy to get into some are too hard to get into and so on 
and the sensation is even more different when not using condom because then you feel other types of differences but of course that doesn't happen easily as you should always use a condom with people you don't know and trust
don't think it would bother most gay guys seeing another guy with a boner in the locker room
still a straight guy might see it as awkward
try to find out the reason why u get a hard on what turns you on in that moment? is it the idea that others see you naked… ? of seeing others naked? does your imagination wander when you get naked among all those naked guys :P?
try staying more naked around home for example to get used to the feeling of it and maybe it wont seem so exciting anymore in the gym either
hope it helps cheers
brooo ur cuuuuute :drool:
as for the face posting part think about it that having a photo of you on the internet can sometimes mean problems. There are alot of creeps and stalkers out there so try to stay safe from them by keeping your identity safe. :ok1:
heeey guys
ce s-a intamplat a murit chatu de tot pe romania?
ye love it
and since mine are kind of "tough nuts to crack" playing with them doesn't need to be gentle
especially love it when someone starts blowing me I'm soft he can go all the way and also lick them i get hard in his throat in a few seconds
Lets put it this way m8
it's your body, it's your choice 
if you don't like something about yourself change that.. but change it for the right reasons not for the wrong ones
change it because you want that because you don't like that
never change something about yourself because you think someone else might not like that.. not many people in your life are worth changing for and besides you might change something under the wrong presumption and end up losing someone might like about you
comando most of the day comando at night
depends on the situation though and season
its a hot thing love it myself
there are alot of hot examples here :PP

have a look (not my personal page but the owner did a good job )
dunno :)) mine is moody too
have a look here for a couple of pics as proof https://forum.gaytorrent.ru/index.php?topic=23218.0
I kind of left this thread to its fate but sadly had no more time to post
still the blog i mentioned is still open and has alot of cool stuff in it
in the meantime i opened my own Thumblr: http://lukeitnow.tumblr.com/
it's alot more pornographic and it contains not just muscle guys but also women or sex scenes/filmes/gifs so be warned :))
its been a loooooong while :)) but here im bored again
enjoy
this is actually a tricky thing 
1 Talking about sex is never inappropriate.. expecially for guys, it's better to know if you actually have the same tastes in Bed
2 think of it this way.. you find a really hot guy that you like and he likes you back and you end up dating 1 month before sex and in Bed it turns out that he bores you to death… now with some people you can work this through you teach them new things you talk and try to make it fun for both... but some will always be boring no matter what so what do you do then... break it off or have a sexless/boring sex relationship...
hope it helps gl
up to this point i have not managed to "function" at 100% while in a 3some :)) i don't know why but my dick never gets 100% hard (so ye my last DP attempts failed because of my 80% hard dick )
kind of Logical if you ask me …cause its hard to get the Bigger one in after you already have something in... but the smaller of the two will make its way around the bigger one easier
well i think I have pretty hairy legs (and chest … and alot of other places.... ye I guess one could call me an Otter :P)
:hmmm: thx for the hint ipertatos but im a Top not really into gettin dped :blink:
