I absolutely love this thread. Finally I found other people who have a similar struggle when it comes to getting an erection in the locker's room.
Just one day ago I had the most "advanced" experience of being naked in the locker's room.
I moved to this new city 3 months ago. I decided to go back swimming because I wasn't doing any physical activity.
I found a very good club swimming club. My first day was one day ago. Right before getting there I realized it would be a perfect opportunity to practice getting naked with no fear or anxiety IF:
1- The lockers room has such a structure that "promotes" nudity (I've been disappointed before by lockers rooms basically made for people who want to hide, like stalls between showers with doors).
2- The people who use it hold a "nudity" culture. In the past, even when I went to very open lockers rooms people would still avoid being naked by all means. Especially if they were mostly young (I'm 23 btw).
So, it all was as expected!
The locker room although has shower stalls with doors, the stall doors are quite transparent which was a bit shocking when I got there to put my swimsuit. There was a mall showering and I could see a lot although not completely. There was another man naked walking (they all seemed to be older than 30 years old).
That was quite an invite for me. I stripped fully naked and put my speedo, slowly. I got a semi but managed to not get very hard.
As I was finishing my swimming exercises I started to get very anxious and nervous because I knew the big moment was coming. As I got in the locker room there was another man there showering alone.
I went to my stall caring my towel and soap, still in my speedo. Right before geeting in there I made sure to get naked before I got in the stall. I took way longer than I would just to make sure we would be both naked in the banches arra. Another man came in and they started to talk.
He left before me and started moving around naked and didn't seem to be rushing or anything. He probably enjoys the mommet or/and feels very comfortable and natural.
That's exactly what I dream about actually: being able to feel included, feel like a real man that makes no big deal out of it. But, interesting enough, in order for that to happen I should probably forget about it.
I related so much to this:
When I was young...well into my twenties, the second part of reason #2 was why I couldn't do open showers, which was extremely frustrating because I fantasized about being able to be naked with guys in these situations. I was so turned on by seeing naked men...and even more so by having them see me naked that an erection was unavoidable.
Not sure what OP meant, especially because later he mentions he's gay. But in my case, my "fantasies" have nothing to do with sex. It's all about the moment. I get anxious even thinking about being naked among other men.
Coming back to my story...
I soon left the stall only holding my towel and naked. I dried a little near the stall and engaged in their conversation. It was bit tough to control my erection but I managed for most of the time. I tried to focus as much as I could in the actual subject. I probably stayed naked and walked around a little bit for at least 5 to 10min. I even used the scale.
A few minutes before I changed I got a semi, then I proceed to put my clothes on.
The second guy had a big penis, which probably lead me to sexualize more the whole thing.
When I got back to my company's building I spanked one in its locker room stall. When I got home I did it again as I got aroused by researching about the subject.
