for me it just sort of happened. When we were younger and just kids we had sleep overs and did naked dares ( see previous post) so were comfortable being naked and hard in front of each other and then I discovered my older brothers playboys and penthouse collection so I told my friend about it and he would come over when ever my brother would get a new one and we would look at it and jack off. Porn is the best way to get it started when you are in high school. You also have to have the right friend. I was lucky.
