As I explained in another topic, I cut my frenulum when I was barely 14 years old. It wasn't strictly speaking for erotic reasons. But it comes a little closer to it. I was aware of my frenulum when I was 10 years old. Since the age of 7, I had discovered that I could "play" with my penis by sliding the foreskin backwards. This made the glans emerge and besides that it was very pleasant, it excited my curiosity. By doing this, I caused the adhesions of the inner foreskin to yield to the mucous membrane of the glans. Gradually, I noticed that by forcing a little, the skin peeled off and the glans appeared more and more. Without knowing why, I felt like I was drawn to pulling more and more to see how far I could go. When I reached the corona, I had to force harder, but when the skin was able to cross it, it suddenly came down completely. For the first time, I saw my glans completely, and I could push down the skin to the base of my penis. I was fascinated! But I noticed that the glans curved sharply downward as soon as I did this. This is how I became aware of my frenulum. I was embarrassed because I realized that it was it who was pulling my glans as well. Naively I tried to pull on it to see if it would come off and free the skin and glans. But of course it didn't work. This finding disturbed me for a little while. Several times, at the age of 12/13, while I was taking my bath, I tried to pull on this strap that was holding my foreskin, hoping that with the hot water in the bath I would manage to detach it. I probably had to pull too hard because I once caused a tear that felt like a canker sore amplified by hot water, which turned red from the bleeding. After this mishap, I was afraid of damaging my cock and I stopped trying to blow the frenulum. A few weeks later, after I had told my grandfather about my problem, he would explain to me how to safely and painlessly cut the frenulum by tying up.
