how do you know your partner doesn't have it? did he tell you? some cases of herpes can so minor that a person may misdiagnose themselves as just having a rash or irritation. genital herpes is sexually-transmitted in 99. 9% of the cases and a person does not have to be actively infected at the time to pass it on. it is very difficult to know the exact type of herpes so oral herpes (fever blisters cold sores) can be transmitted to the genital area during oral sex. if you have only had one partner then the source is likely that one partner. if you have had more than one then it could have been any of them.
how can i get herpes 2 if i have not been with anyone who has it? . i know my partner doesn't have it.
