They take a shower with hard dick and pretend that nothing is going on down there… ;D
I also have hard dick sometimes after workout. Guys usually ignore it. Or just ask me how big it is...or tell me if I know I am hard and that I should jerk off at home because I have big balls and it seems they are full of cum And they are surprised when I tell them, that I jerked off today and thats my normal size of balls... But thats all.
Usually very young guys (teenagers) are ashamed and trying to cover it. Walking with their hand on hard cock. There was very young boy (probably like 15 or 16) sitting at the bench in locker room, next to my locker...and he had both hands on his cock when I walked into room. But he has bigger one and the top of his penis was sticking out of his hand. I asked him wtf he is doing and he told me he is waiting for his erection to go away. So I told him, he is young and those are all those endorphines from working out...thats normal and he should ignore it and go to shower with me...and he seemed happy, that someone understands...we went to the shower (noone else was there) and you know, i liked his body and cock, so I was hard too...put away my towel and said "look surprise" he was laughing and said "you too?" and I said...you know...those hormones after working out, buddy we were taking shower and he said if he can ask me something...and I was like what? and he said he has some white spots on the head of penis and he is afraid if its not dangerous..I knew, what are those spots...but I gave him handjob for a few seconds and was like "ahaaaa I seee, those one, I have them too, touch my penis and look" and he grabbed the head of my penis...and then I told him those are "pearly penile papules" and its absolutely normal anatomy of penis...and almost all guys have it. He was the happiest boy in the world. He asked me if I am really sure its not some STD and I was like no, its not, its normal...are you a virgin? and he said yes. Then how can you get STD when are virgin. And he said "I dont know"...then he asked me couple of questions about my penis...how big it really is...that he wants to have hairy big balls, like I have...how many times per day I jerk off so we had nice shower chat and thats all...
I think there wasnt anything sexual in it...at least not from his side...they probably dont talk about those things in his family and he doesnt have older brother or cousin to explain it to him.
Since then he always wants to workout with me, when we meet at the gym and he wants to take shower with me too. And he is permanently spamming me with messages on facebook and you know, teenagers can be very annoying...and he is sad now, because gyms are closed due to lockdown...
And my weirdest experience from the gym was with one bodybuilder, who likes to workout in the evening. And he loves to jerk off at locker room and eat his own cum. I have seen him doing it couple times and I asked him once, why is he doing it and he said, thats free protein and cum after workout is full of testosterone and I should eat my cum too And I said that I dont like my own cum, but I can cum too and he can eat it...and he was like "wtf dude? are you a faggot? thats disgusting" And I was like "ehm OK, sorry...I thought you want free protein"...and he said "but I am not gonna eat your cum dude, that so gay"... But he doesnt mind when I watch him doing it and I usually just stand there with erection...
