J.S.
To answer you question, no. Just because you don't like the diagnosis doesn't make it wrong, sorry. You were treated and it is gone. Why exactly do you care at this point? Do you want to think you had sex with an amazing guy that wouldn't put you in danger or an STD. I mean do you hope to continue having sex with him?
Don't make excuses like the labs might be wrong. If you want to continue the relationship then do it. You don't need us to approve of it
