I had sex with this girl around August 20th. Just last friday (9/21) as I got back from the gym, I noticed this round bubble like thing on my penile shaft. It wasn't small, in fact it was decent sized, and it was by itself.
I waited till the next day, and noticed it had puss inside, so I ruled it out being a wart. It was either a pimple or a herpes sore. It was very firm and hard to the touch. I only felt a little pain when I pushed down on it with a finger. It didn't itch or hurt normally.
Over the weekend, I got impatient waiting to call the doctor, and I popped it. The puss came out (along with a little bit of blood), and the bubble flattened.
It's been over a week since then, however it looks as if the place where the bubble was has scarred? It's flat now, but it looks like a pink colored flesh scar you would see elsewhere on your body.
So far, no other bubbles have popped up. The scar doesn't hurt or itch, and I urinate normally without pain.
Is this herpes? Or was it just a pimple? I looked online, and they said you shouldn't pop genital pimples since it could possibly scar, but it's too late for that now. I will be fine if it is simply a scar, and not an STD.
If it helps, before the bubble popped up, I went to the gym multiple days before, and didn't shower because of depression. I remember peeing at the gym on thursday and didn't notice anything. Then a day later it seems to of appeared out of nowhere.
I didn't tell the girl, but I did ask her when's the last time she got tested. She actually told me that she got an STD test AFTER we had sex because she was worried about the same thing, and she said she came up clean on everything. So I don't know if she was lying, or telling the truth, and I just got a pimple from not being clean.
Can someone please help me? I got blood drawn today for an STD test, but I won't get the results back for another week.
(P.S. I don't have any pictures of what the bubble unfortunately, just the aftermath. Also, I went down on this girl, so if it was herpes, shouldn't I have it on my mouth as well?)
