I am hiv possitive and im also taking medication. I am now undetectable but my isssue or questions are regarding my sex drive i always been a very very sexual person but now its hard to get myself. Into the mood and i talk to my doctor about. It but nothing has changed even when she changed my meds i dont want to loss my husband over this i need help or a better understanding. I kno my body has changed alot over this n its still.
