When I was about 15 I somehow got the idea all on my own to use hot wax on my cock/balls. I hadn’t seen this anywhere it was before the internet. This led to shaving them bald. I liked the pain and I loved how sensitive it was during masturbation.
When I hit 16 I became obsessed with being exposed outdoors. My parents house bordered on a small forest, we had paths and BMX bike jumps out there. I began going out at night and stripping nude to see how far I had the balls to go. When I hit my limit I’d madturbate, after I came I was overcome with shame I liked that feeling but didn’t know why. So it progressed to the point where I would leave all my clothes behind and hike an hour nude. Occasionally I’d get to the side of the highway Rte 80 in NJ, I’d walk out there totally exposed. As my need for a thrill continued I started doing the wood hike in daylight- almost caught several times. It wasn’t until I got to college that it all came together.
