Hi Doctor, I wanted to ask you about a recent encounter I had with a call girl. This is everything that happened. My penis was limp at first with the condom on, and I could not get penetration. But after it became erect, that is when we had vaginal intercourse. It lasted no more than five minutes. To tell you the truth, I never had an orgasm. It was hot in the room, and I was pretty tired, so I decided to just pull out. I remember the head of my penis was covered when I pulled out. The condom seemed in tact because I visually inspected it after our encounter. I m thinking that I should be fine. But would you say that I have risk for STD or HIV?
