The first glimpses I got of a real male penis and testicles was up the leg...I discovered this in about 2nd grade and even today in College it is steal my favorite method of observing male genitalia.
The first glimpse I got of a real penis and testicles was up the leg when boys would wear either short or wide legged shorts sometimes when a boy would sit down I would get a straight shot up the leg and see their wrinkly scrotum and if I was in the right position I could also see their penis. From the age of 7 up until the present I had seen a variety of male genitalia that way. I remember one boy in particular way back in the 7th grade that I could always count on to see his genitals up the leg of his shorts because he always wore very loose boxers and relatively short shorts compared to other guys his age. Anyway I remember at P.E. we were running aroundand he was exhausted and plopped on the ground and when he sat down one of his testicles came out and I could see his penis and that he was starting to grow some pubic hairs. I do not think he knew because he was hot, sweaty and trying to catch his breath. What a perfect opportunity to get a good look at his penis until he got up and continued to exercise. All day long I could not nor did I want to get that image out of my head when I got home I fantasized about seeing it again while I touched myself and fell asleep. The next day sure enough he wore shorts and I was ready for another peek. When he sat on the grass this time his testicle did not come out yet it was still visible and so was his penis as he sat on the grass exhausted after running acting more tired than I really was I plopped down next to him and got a closer view of his foreskin covered, light brownish penis, his few brownish pubic hairs and his wrinkled scrotum and when he sneezed a few times I saw his scrotal sac contract or jump I guess, either way I was aroused. Over the years I got to see his and many other males that way (up the short pants leg)The images I would collect during the day were part of my nightly masturbation fantasies up until this day. Now that I have a boyfriend we often role play that I saw his penis for the first time up the leg of his shorts.
