l was the only person he had ever had sex with and l had sex before...is there any other way to get genital herpes without having sex? l also checked with the previous guys and they did not have it.

If your ex had never had sex with anyone else other then you. But you have had sex with other guys. Then more then likely you gave him the herpes.

Even if these other guys you have asked, said they didnt have any outbreaks, doesnt mean that they do not have herpes.

Herpes can go undetected FOR YEARS. as it shows no sypmtoms in some. But it does show symptoms in others, such as your now ex bf

you can have it without shoeing symptoms, but you probably have it if you were having unprotected sex with him while he had it, get some herpeset
