Hi, I was wondering if I have caught any sti lately. A few months back I had a sexual intercourse with 1 girl and yes it was a protected one, I wore a condom. This afternoon, I felt something on my pubic area and it feels like a small bump, I think it?s an acne/blister on the pubic region, so far there?s no other symptoms than that. And no I am not taking any medications but I do have sinus since I was a child. I?m 18 this year and my height is currently 172 cm while my weight is 75 kg+
