So I have had unprotected sex with my girlfriend multiple times over the last month or so, and sure assured me she was clean, however neither of us had been tested prior. I noticed a small reddish bump on the base of the shaft of my penis, and am not sure whether it is herpes or an ingrown hair. It does not hurt to pee, nor does it hurt to touch. I tried to pop it at first, and a little blood/ puss came out originally (about 4 days ago) but nothing since, because I have not touched it much. It seems to have gotten slightly smaller, however it is still red and raised. There seems to be no other spots such as this one, there are a couple smaller bumps near it however they seem to be hairs and are not red or swollen. I am very nervous that this is an STD such as herpes, but it seems like it might only be an ingrown hair because it does not hurt and I seem to have no other bumps or sores anywhere. Any advice would be greatly appreciated!! I will be going to the doctor soon however I wanted to see if anyone could tell me whether it is only an ingrown hair first. Thanks!!
