Attempted bottom but it just would fit very good. Maybe a little more then just the head and a condom was used.This was done through gloryhole so I don't know the status and didn't last long.
You used a condom? Even if it slipped a bit, as long as the head of your penis was covered, you did not expose yourself to HIV. HIV is only transmitted by unprotected vaginal or anal sex or sharing of IV drug needles. So, this is not a risk.
