Okay. So I am super nervous right now because I have around 15-20 little bumps come up, kinda in a row, around the head of my penis. I Have done extensive searching online for answers and I am 80% sure that it is probably just genetics and not an std not anything to worry about. Regardless of it possibably not being an std, I still don't know what to do about them because they are embarrassing and I want them gone. What should I do and do most health departments give you a free blood test?
