What is the risk of unprotected sex for the negative active partner from

[Guest guest]

I keep hearing different risk levels for transmission of HIV to the

negative active partner from the positive and undetectable passive

partner. First there was the Swiss study that said the risk was very

very low, then came the Australian study that said not so fast, and

subsequently I have read several articles on the risk but those were all

based on the premise of a positive active partner and a negative passive

partner? I am positive and have been undetectable for 10 plus years,

and my boyfriend who is negative and is the active partner have

unprotected anal sex. I know their is always some risk but I would

like to know what the real risk level is? Cheers.
