Gym locker room and shower

I’ve (M20) been going to the gym for a while now, and it has a locker room with cubicle showers. Each cubicle is divided up and each one has a curtain.

The thing is, that to be honest thats my favorite part of the gym, because I can watch more guys naked and taking a shower too. I like when I finish my workout in the morning and then in the locker room I can get naked and take a shower.

Since my entry to the gym is quite early in the morning, Im no longer watching more guys because no one goes too early. And last time no one else entered while I was there, so I was fully naked, with a boner, and while taking the shower I would close the curtain, but since I read they arent exactly clean, Im planning not to close it (also an excuse to show off) but does someone else share this feeling with me? To show off like accidentally, or just be naked as normal?

The only thing that makes me worried is that often I get a boner, and ngl I try to cover it. Would you think is normal to have one and not care and let everyone watch me? Or should I cover it up for respect? Feel free to talk to me if you share this feeling!
