The circumcision I had in my mid teens. Well, not the circumcision itself, but the erections I would get in the morning which would rip the stitches out of my cock, bleeding until I masturbated with anesthetic gel to orgasm just to stop the pain.
Indeed. I hadn't realised that the skin should be able to retract over the glans until a friend had mentioned an encounter with a lass. I thought... eh, over the head? He confirmed yes, over. So, I went home and tried it. Fuck me that hurt, I still have the scar despite the circumcision. Told my mum, went to the doctor, confirmed yes, need to chop chop.
