When/why did you get into nudity?

I've slept nude since elementary school. Once I reached middle school an incident happened one summer with a girl that caused me to realize I was an exhibitionist. I started spending all my time alone in the nude. When I was in my bedroom or home alone I was nude. I eventually started sneaking out of the house naked to explore the neighborhood at night. I'd also hang out in the backyard naked eventually and after that I'd even end up becoming a nudist.

It just felt so good and comfortable.
