Hi there, 

Firstly i just want to say a big thanks for running this forum, it's a great resource. 

So I'm a 23 y/o male FYI. On Saturday I had a wild night drinking and things ended up getting hot and heavy with 2 partners afterwards, a hetero male and a female. We were going to initially have a traditional 3 way but we decided not to as the girl was recently coming off her period. What instead happened was that the girl gave both of us guys head, swapping between us, with me finishing up first and showering immediately after. This was all without protection. I had absolutely 0 direct physical contact with the male, his genitals or his full ejaculate and no homosexual relations took place.

I've later found out that the guy has once had unprotected vaginal sex with a female sex worker, which has caused me to absolutely freak out ever since. I had a small cut on my thumb during the time of this sexual encounter from around 24-48 hours earlier from a knife whilst cooking (so was extremely unlikely to be actively bleeding) which I've attached as an image. I know it might sound ridiculous, but what are the chances that HIV would manage to survive the transfer in pre-cum via the female's mouth or hands and into the cut on my thumb when I was touching my own penis. Is it highly unlikely HIV in pre-cum would survive this or should I be concerned about it? 

I've spent hours researching but I can't find anything about whether the HIV virus can be indirectly passed using the mouth. Any help would be greatly appreciated as it's really affecting my life currently, I cant eat or sleep due to worry. Thank you in advance.

Hi there,

Thank you for your inquiry. From what we gather from your question, you are asking about possible HIV transmission from someone who was alternating performing oral sex between you and someone else. 

To begin with, HIV transmission is NOT dependent on the sexuality of an individual but by the activity that is involved. For example, transmission is equally likely from someone who is heterosexual compared to someone who is homosexual for certain acts of sex, such as anal receptive intercourse. In the interest of HIV transmission, we focus on the activity and not the person involved in the activity. 

From the information given, this scenario is determined to be of Negligible Risk (there is no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances)

Transmission is considered to be of Negligible Risk for the following reasons:

HIV does not survive in saliva so if there was any HIV present in the other person's pre-cum, it would greatly affect its integrity (1). Additionally, exposure to oxygen further decreases the concentration of HIV present rapidly (1). Although the three components of our Transmission Equation (see below) are technically met, the situation you describe under the given circumstances results in transmission being of Negligible Risk

Please refer to our HIV Transmission Equation below for more information:


Recommendation: There is no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers.
