Hey I'm 16 years old and i have had these sores below my belt line for a while now. I have two and thy are about an inch away from one another. They stay pretty small but sometimes (I think its when my pants rub them the wrong way) they start to sort of grow? No sure how to explain it but they seem to grow sort of like a pimple except much larger and they soon bleed and pus a bit. After that they stop being painful and just look like a scar, but soon they will grow and become painful again. Im not sure what they are but i know for a fact it isnt herpes. If someone has an idea of what to do or what they are just let me know please. Im worried and may go to the doctor soon.. I had them before i lost my virginity.
