I am 13 years old and not started puberty yet. I am allergic to different things and I tend to break out a lot if my skin gets irritated. I had another little occurrence 4 nights ago when my allergies came on and due to my morning wood my penis scraped against my underwear
Causing to middle of my penis to get irritated and get a small red bump on the top middle. I am a virgin so I doubt its an std but I do masturbate frequently. It is a little bit itchy but so are the other bumps all over my body. I have not touched/scratched/masturbated ever since I found it. It is almost gone now but I am still very worried and wondering what should I do. I am very embarrassed so I have not told anyone. I am extremely worried so don't poke fun at me and help me as much as you can.

There is nothing really that you can do. Just let it go away on its own.
