Well today I was working out at a new gym. So after I had my workout I took a shower. This where communal showers with no dividers or anything. Im not used to that but I also dont have a problem with that. So the shower room was empty. And there it happens, while I was having my shower I started to get hard. First just semi. I tried to distract my thoughts while turning the shower heat down. But it wasnt really helping. Then there came someone out of the steamroom, he took a shower in the corner away from me. I actually started to get fully hard. At first I though, well just wait until it comes down. But I wanted to prevent the awkward moment when the other guy would notice my boner. So I walked out of the shower room past the dark doors from the steam mroom and sauna before I could grap my towel. Luckily there was no one in the changingroom so I could quickly put some boxers on. While being almost dressed the other guy from the showerroom comes to the lockers and starts having a chat with me while being but naked. At that moment I didnt know what to think, did he notice my boner?
I dont intend to make a problem from this but what should you do? Quickly get dressed or just keep showering even when others can notice your hard on?
I agree with posters who note hard ons in open showers are not acceptable -- when brought on or encouraged in purpose. I think you managed the situation well.
First, like others said, I would try to bring it down by retraining your thoughts AND giving it time. If you can face wall or keep turned away from others in there, take your time see if it wilts.
Nobody is likely to say anything about your condition (most will sympathize and understand) and you should not say anything to explain. This does happen; not a major crisis.
If your member declines to simmer down you head for the towel in a relaxed manner and cover up.
If I saw a dude in showers w a stiff one I would think "bad timing, poor guy" even if kept on w his shower. If I saw him walking across the locker room with a hard penis with a towel over his shoulder I'd think he confused the gym w a gay bathhouse and he's being inappropriate.
Most guys fear this problem but then in the situation it does not happen. You report a recurrence of the problem, and now that you are worried about it, and it does happen, it will likely keep happening for awhile. Just keep showering, take prudent steps like picking corner shower heads and proximity to shower hooks and eventually (applying some good advice of others here) it will stop.
You may want to masturbate before heading to gym. Works for some guys.
Also, in your situation where the cock is reacting to naked stimulus -- that is to say you get naked and under hot water and he rises to attention reflexively and repeatedly, you may want to try something like this:
Watch great porn that gets you very hard right before you go to gym without masturbating. The porn gets the dick up and identifies obvious sexual stimulus. This puts in perspective what you will experience in the showers as "not that" .
I know a man who reported that if he masturbated to completion or even had sex, the dick down effect of that lasted only a short time. But with the porn no masturbation technique he was ironically very horned but good to keep soft in showers. He actually reported ultimately just listening to familiar porn on his smart phone as he biked to the gym! He gets off bike hard, pulls out earbuds and by the time he gets into the locker room to stow his backpack he says he's soft and stays that way through his workout and then his shower after. He may be only person on earth this works for, but it makes sense to me.
Time alone and trying nothing other than going regularly to gym should solve the problem. Be patient.
