Nudity is standard in my family. My parents roam freely around the house completely naked, and I grew up doing so. Eventually, as I developed, I began to get boners during the day. It was often noticed, and so one day when I was 12, my dad came to talk to me. He asked if I masturbated, and I said that I had been masturbating for almost two years. He said its great to do so, and that I should keep doing it constantly, and not to be embarassed with them at home. I could do it wherever I wanted to, and they wouldn't mind.
So I masturbate constantly, to porn pics on my computer and in magazines, in the jacuzzi, the pool, or just outside in the sun. My parents are awesome, and constantly encourage me to masturbate.
