In my gym in Italy about 10 years ago the showers were almost full - 2 lines of 5 showers facing each other - a new guy walked in and started showering. He was directly in front of me, in his 20's and fit. When he turned around he was totally stiff - not a bit pumped but pointing skywards. He carried on washing but then realised the other guys were staring at his dick. He ran out his dick bouncing in front of him. Seconds later he returned to get the shampoo he had left behind. The rest of us laughed - poor bastard!!! I never saw him again.
I felt for him as it had happened to me when I was 11. AT my secondary school I had put off showering with the other boys after football by forgetting my kit or being ill. By the 3rd week I had to do it. I stripped off and went in with the others. I chose a shower at the end of the long room next to a big lad I knew called Geof McCatty who boxed, he was very muscular and hung - I stood under the shower until someone shouted out that I had a hard on. I didn't realise it was me or why I was in the wrong to start with :) . My dick soon shrank but it was a horrible experience. I beat off 2 or 3 times before games or PE after that for years afterwards. What a trauma twice every week.
Recently I saw a hard dick in German in a ST8 sauna - everyone was naked and it was mixed - a guy in front of me in the showers was stiff and his girl friend was laughing. Nobody paid much attention.
In my gym in London the shower room is open and next to the changing area. Lads get half hard all the time because there are lots of fit guys and most are gay. I have seen quite a few horizontal dicks. NO one ever says anything - a few lick their lips :) 1 guy made a video of himself beating off and put it on the internet!! You can see his face and the other guys in the shower who clearly don't know they are on film. It must of pissed them off quite a bit !!!
Long live communal showers!
I fear they will be extinct within 20 years in the UK :(
Lets hope I am wrong :)
