Hello,

I hope you can help me.
I recently hooked up with a guy I don't know in a cruising area. As far as I can tell, I was safe.
He gave me a blowjob and we used a condom. However, he normally practices unsafe sex I found out.
My question is - how high is the risk, if someone else had ejaculated in his mouth before he gave me a blowjob? I don't know, but there might have still been some sperm in his mouth?
I would be very grateful for a quick reply, many thanks!

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV by receiving oral sex with a barrier. From the information given, this scenario is determined to be Negligible Risk there are no evidence or no documented cases of transmission. However, there is a theoretical possibility.

1 To be at a risk of acquiring HIV there must be HIV present in a bodily fluid. Semen (including pre-ejaculate) is known to transmit HIV. Taking your partner's ejaculate in your mouth appears to make transmission more likely (especially if there are any cuts or ulcers). Using a barrier such as a condom during oral sex can reduce the risk of transmitting HIV.

2 There are not enough reports on how long can the sperm survive in the oral cavity; factors like food and pH of the saliva can affect it (1) However, even if there is presence of ejaculate in the oral cavity; as long as there are no bleeding sores or ulcers in mouth the risk of HIV remains Negligible because essentially there is no direct mode of transmission to acquire HIV.

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