I had a bump on my pubic hairline that was painful to touch when trying to squeeze out whatever was inside, which was a clearish bloody looking fluid. I thought it was an ingrown hair, so I tweezed the hairs around it. The bump itself is gone, but it has left a small hole behind. I had unprotected sex with someone 3 years ago, I said no when he said he didn't have protection, but he didn't listen. Could it be an STD? And what type? It hasn't spread anywhere, but it is worrying me.
