I have a bump on the underside of my penis that appeared right after visiting my girlfriend and haveing sex for the first time ever. Im not sure if it is an std or a ingrown hair, shes only been with one other guy. I did shave down there right before i went to see her. Ive messed with it and it has made it bigger, ive also pulled out a lot of the root of the hair folicol that it is surrounding. It now looks similar to a wart, i dont know if thats just because ive been messing with it or if thats what it is. Ive had it for 3 months and its only gotten bigger, it seems to go down when i pull out the white hair folicol/root but it keeps coming back and i have to open the skin to get to the root, so ive been doing minor surgery on myself, which probably isnt good.
