I actually don't think this is an std but I don't know where else to put it. Since about the age of 7 I've had small bumps under my fore skin and and a few years ago they appeared around my urethra. They form in clusters, cannot be popped and and are pale in colour. They are not fordyce spots as I looked them up. These don't appear along my shaft, only underneath the foreskin. I have good hygiene and shower every day. They've been spreading very slowly over 9 years as I am 16 What is this?
