Well, I'll post the first time I got arroused by it. I must have been about twelve, I had known and played with a certain girl since early childhood, she was of the same age. She had brown hair, pretty straight to her mid back. When we where alone in her room, certainly later when we where just playing around or sitting on the bed listeining to music, I just loved to touch it, run my fingers through it or even just put my hand behind her in her hair. And one evening, I can still remember it well when it turned me on for the first time. I'm also pretty sure she was the first girl I jerked off to in my mind. Shame her parents had to go and move to another city...
