If a HIV negative man comes inside a HIV positive woman what are the risks to the man?
What is the risk if a negative man having sex with a positive woman uses a condom but then when the man is about to come he takes off the condom and he comes inside of the woman? Will the man be infected?
Thank you for your question.
Any risk is not related to whether or not you cum, but to other factors. These include how long the contact lasts (in this case maybe just a few seconds) so the risk will be very low.
If your partner is taking HIV treatment and has an undetectable viral load, then the risk will be zero, even if you don;t use condoms at all.
The biggest risk of transmission relates to viral load. When this is undetectable the risk becomes zero then transmission doesn’t occur.
Are you asking this question so your partner can become pregnant? If yes, the it is easy to still conceive naturally, but better if your partner is on treatment.
