hello. i have been having unprotected sex quite frequently (several times daily) with a girl who recently confided in me that she has engaged in quite risky behavior before we met just a few monthe ago. we are now both waiting for results from std tests. My question is: if one of us were to have something, given the fact we've had unprotected sex hundreds of times, would you say it surely had already been passed to the other? I mean, should we not have sex at all untill the results are in?
