I'm currently experiencing a very strange problem. So just for info: I'm 16 years old, male. Around a week and a half ago I did something very...ignorant. Out of curiosity, I tied an elastic band around the bottom of my penis shaft while masturbating, as I've seen online that it can make the penis more erect (I wasn't having any erection problems before, It was just out of curiosity). To my success it did. I didnt have on the elastic for long. I would wrap it on my penis (not too tightly, I made sure not to make it too tight), and then after 20-40 seconds I take the elastic band off. I did that 2-3 times. The last time I wrapped it on just a little bit tighter, and it made the erection better, but as I took it off something a little frightening happened: my penis started to loose its erection entirely. I couldn't get hard or anything. I wasnt experiencing any pain, swelling or discomfort. It just wasn't getting erect. I spoke to my mother about it (embarrasing conversation) and she told me the nerves were just irritated. Which I think were right because the next day after the incident, I was getting erect again. But I noticed something off, the sensitivity that I had in my penis before just wasn't there anymore - especially around the frenulum of my penis.
I thought "oh maybe it will come back" so I just ignored it. But since then, nothing has changed. It's like the sensitivity in my frenulum has just decreased. I really hope its nothing serious. Does anyone know what may be happening?
