I think I was eleven when i first started noticing that my dick was a sensitive area.
I remember the first time a came too
. When I first started masturbating, i did it only to feel good while touching. Then one day, while standing in the bathroom, touching myself, I felt this enormous feeling flowing through my body and my legs just turned to spaghetti. After that extreme feeling had gone away I just couldn't touch my dick anymore (it hurt at that time). And man was that the start of something frequent to come ^^.
