HIV Risk of "Docking" with a Large Amount of "Pre-cum"

Question: 

I recently had a sexual encounter with a cisgender man (I am also a cisgender man) of unknown HIV status. I am negative and not on prep currently. We did NOT have anal intercourse. However, we did engage in "docking." Both uncircumsized. There was a large amount of precum from him and he was also using this as lubricant as he was rubbing/jerking off both penises together during the non-docking/mutual masturbation. Just wondering about the potential risk for HIV transmission if said individual was positive and not with an undetectable viral load--the reason I ask is because of the amount of precum and wondering about my urethra and whether any could get in and potentially pass on HIV. New to this activity and likely won't do it again with guys and thanks for your help. His penis was also quite large and I was wondering whether this fact--including the penis going into the throat--carries a greater risk for oral sex without a condom.

Answer: 

Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through docking (connecting the head of ones penis into the foreskin of another).

For a risk of HIV transmission to exist, specific HIV+ fluids must come into direct contact with the blood stream of a HIV- person. Only some bodily fluids carry enough HIV to pass the virus sexually such as semen, vaginal fluid and rectal fluid (this includes pre-ejaculate). Further, wet skin such as the urethra of your penis contains mucous membranes susceptible to HIV transmission. In your case, the act of docking between you and your partner, with a considerable amount of pre-cum, does carry a potential for HIV transmission.

Although this act presents a potential for HIV transmission (due to the exchange of bodily fluids, with direct access to the bloodstream through the urethra), there has technically never been a confirmed report of HIV transmission. For this reason, we would consider the scenario provided to be of Negligible Risk (There are no evidence or no documented cases of transmission).

While there has never been a documented report of transmission through this avenue, it still remains important to know your HIV status.

Recommendation: There are no evidence or no documented cases of transmission refer to Physician for more personalized answers.

All the best,
