Well, it was in the gym shower at school when I realised that my flacid cock was much smaller than all the others.
I was 14 then and I was really worried. I even consulted our school doctor but after examining me he said everything was ok. I was not satisfied with his answer and only later found out that I was what you call a "grower".
My sex life has always been fine since then but I still envy those well hung men, especially on textile free beaches and in shower rooms. But you have to live with what you have got, haven't you?
