Hello, i recently had a lump in my pubic hair that was hard and firm, somewhat nodular, that scarred pretty bad as i tried to pop it like a pimple. Recently i again developed a lump now at the base of the shaft of my penis in a hair follicle, i pulled out the hair but it did not get better. It has been there for a few days now and it feels very hard like a nodule and is the size of a pea, it grew i size after i attempted to pop it. I am worried it may be an std because i did have unprotected intercourse about 2 months ago. Please advise.
