Hello I am 16, and last week when I was in the bathroom I noticed that a little red bump had appeared, it didn't hurt itch or anything, the first 2 days it got a little bit bigger but not any much then it started to shrink again and spook less red, but today, 7 days later, it was the smallest it had been in the morning, but 12 hours later it looked a little purple and kinda hard, lshe when you get a cut and it heals and a little of that stuff falls out? Well that happened on the bump and it fell of and a little blood came with it. Im really worried about this although it doesn't hurt itch or anything, I had thought it was a pimple because I get them very often in face and I liked just like a pimp(although the lump was smaller, someone help, thanks...
By the way, it's not on the penis, but like on the skin above it
