If you’re in a relationship, you may not need PrEP. For closed (i.e. monogamous) relationships, if you have both tested for HIV and are negative, PrEP may not be necessary.
If your relationship is open (i.e. not monogamous), you need to discuss with your partner whether you and/or your partner(s) should be on PrEP to reduce the risk of getting HIV.
The situation may change so it’s good to have open and honest discussions around your sex lives to help you decide.
