Was with same partner for five years who had cold sores. Two years ago he tried Valtrex for an outbreak, cold sore cleared, we waited about a week before he performed oral sex. About two days later I developed a really small but quite painful vesicle on genital area, went and had cultured but was negative although physician felt that it was most likely hsv given the history.  I have never had a recurrence until now and this is full blown and agonizing.  Have gone for repeat cultures, unconfirmed as yet, but not much doubt as pretty classic symptoms.  I am not with same partner and had sex with a new partner and condom had a rip which we didn't notice right away.  48 hours later I developed massive outbreak.  This partner is telling me that he had just recently had std testing (negative for antibodies) , has no symptoms now nor ever has, and no other partner except for me since being tested. 

I want to give him the benefit of doubt and that he is being truthful about not being hsv +, but: 1. could he have and not know because always dormant  2.had testing but false/negative perhaps or 3. maybe was infected but had no symptoms and testing was performed before antibodies were present?? Could there be a chance that I did become infected two years ago and it was dormant for me all this time, and coincidentally flared after having unprotected sex with a new partner?  My physician feels that the coincidence is just too great and that I contracted from this new partner given the unprotected sex and rapid onset of symptoms.
