I was 14-15 when exposing myself became a turn-on for me. The first few times it wasn't me who started it puposely, but a girl named Caroline. The trailer my parents had was set up in a very nice resort park. My bedroom was in the back and I was sure I saw Caroline looking in at me from the bottom of the window when I was nude. I'm not sure now whether I was embarrassed about it, but I do remember getting an erection thinking about her seeing me naked. Not that I was especially built well or had a large penis, it just excited me. I was there two or three weekends a month and most of the summer when school let out. Caroline was a tomboyish type of girl but also pretty. I knew her well and often hung out with her and other girls and guys from the campground. Her trailer was next to ours but turned on an angle. I began watching her sneak around the woods and come up to my bedroom window. I would only open it a crack but always knew when she was watching me. For a long time she only saw me naked after I had showered but if my parents were out I would stay naked for longer periods of time. Knowing she could see me made me get erections most of the time but I never tried to hide it from her. I think 5 or 6 months went by before I began letting her watch me jerk off. As well as I knew her I felt secure about doing it because she didn't go to my school. I would watch from the top of the bathroom window waiting for her to come over to our trailer in the evenings. I had to stand on the toilet seat because the bathroom window was high up. One night she brought Kelli with her and I was so excited by it I stayed naked for over an hour before letting them watch me jerk off. For over a year I did this on a regular basis and know for sure ther were six girls who saw me naked and masturbating. I was dissapointed the following year when my parents sold the trailer and bought a cabin. What I reget now, since I am 27, is that I see both Caroline and Kelli frquently in town and both know my wife. Theres one of the other girls I see sometimes but I forgot her name. It never embarrassed me when I was doing all that but it does now. That was the only time I ever did that kind of thing and once my parents bought the cabin never did it again. Today I wouldn't consider doing anything like that.
