A while ago I had sex a bunch with a girl in one night and the next day I got three what looked like ingrown hairs around the base of my penis. One was worse than the others. I popped it and they went away in four days to a week. I used condoms andthought that the ring that ends up around the bottom of the shaft had rubbed the area a lot, so i made the assumption ingrown hair. A year later i got tested and came up negative. Still a little worried cause when i had sex with condoms after that for longer periods of time they came back. Should i get tested again or stop worrying?
