Q and A


I’m undetectable, can I transmit?

I am HIV+ Gay man and undetectable for over 2 yrs. 100% adherence and fit. My BF is negative and on PREP we do full STI check every three months. We’re in an exclusive relationship. Lately he is asking me to ejaculate in him and I am very anxious about that. Is it ok to ejaculate in and him not get infected ?


Thanks for getting in touch.

The simple answer is that no, you cannot transmit HIV to your partner. You can’t transmit because your viral load is undetectable. Please see here: http://i-base.info/u-equals-u/

Because there’s no risk, your partner doesn’t even need to be on PrEP.
