When I was in school (middleschool and highschool) I used to tuck my penis in between my right thigh and under my balls because if I didn't do that id pop a boner out in public in front of everyone just from talking to a girl. And the conversation could be about anything. Any kind of talking to a girl made me pop huge erections without fail so I learned to just tuck my penis everytime I went outside everyday for nearly a decade. I remember measuring my cock when I was a freshman in highschool coming in at 7 1/2 inches then measuring my penis a few years ago in my early 20s coming in at yet again 7 1/2 inches. Is it normal for penises to stop growing at age 15? Did I stop my penis from growing because of the decade long tuck? Did anyone else here measure their cocks before and after in those age ranges and not notice any growth? Would really like some insight on this
