Possible Exposure to HIV via Pilonidal Sinus

[BenSmith20]

Dear Doctor, Yesterday I engaged in a non-penetrative sexual encounter with another guy. I have a Pilonidal Cyst above my anus which is not actively bleeding and does not hurt (I suppose it is not infected). We did not have any penetrative sex, however he did pre-cum on the opening of my Pilonidal Sinus (The hole). His penis opening was right on the tract opening when he pre-came, meaning the pre-cum was only briefly exposed to oxygen. I am extremely worried this might be a route of HIV transmission. Would you advise me to try and get PEP? Kind regards, Ben

While I know WHAT a pilonidal cyst is and WHERE it is most commonly located, I have never had anyone ask about a PC in regards to anal sex.
I would assume that you could still have anal sex if the cyst was not actively infected, but I think you would have to be very diligent about not putting pressure on the cyst. This would mean certain sexual positions would not be a good idea.

What I DO think my best advice would be is for you see an HIV specialist and get far more accurate information than I can give you. The MOST important thing is that you remain safe and I'm afraid I lack the knowledge to advise you how to do that.
I wish you the best

It is not a question of having anal sex, I am wondering whether I was at risk of contracting HIV by having pre-cum on the sinus opening.
