Enough...test 3 months post exposure to know your status. Simple as that.
To know my status, but that don't make sense. Obviously I'm negative if she was negative after me and after the window period and I had her 3 times unprotected? :s or does that not mean anything or make a difference? :s
Not all unprotected sex will lead to infection. Meaning, even if you had 3 times unprotected sex your girl, that doesn't mean she'll get infected.
Try to repost you question with exact exposure you had.
It's like this: If you had unprotected vaginal/anal sex with somebody whose sexual pattern is unknown (I mean outside your marriage/domestic partnership/relationship), you would need to get tested 3 months thereafter, because if she/he had HIV, she had a chance of transmitting that to you.
Any negative result by then will be conclusive.
So its not allways passed on just depends on luck??
