Juvia, first of all, I loved your post. The way you described everything was real and beautiful and you're obviously a really intelligent chick. I found out about my HSV status only about a month ago, so I'm still trying to decide how I feel about it myself. I think it's kind of like a roller coaster. Second of all, PeasNCarrots is right. I don't think you should be so hard on yourself about the situation with your ex. The good thing is that he was a consensual partner who chose to have sex with you while knowing there was a possibility of getting it too. (Of course) this is just speculation, but, he says casual sex is something he doesn't look forward to giving up, so, it's safe to say he might engage in casual sex (maybe even with a person who is HSV positive). There is a possibility that you gave it to him. There is a possibility you didn't give it to him. You'll never know but, should you live with intense guilt over a possibility?
And I think you and I share very similar HSV contraction experiences. I'm wondering if the difficulty you're still having in coming to terms with HSV is because it came from a not-so-wanted sexual experience. I'm not sure how long it takes someone to come to terms with the H status, but it seems you might want to look into that aspect of the situation if you haven't already. It may be part of your acceptance process. Just a thought, I'm totally not an expert at all but, girl I feel your pain. AAAnnnnd, I'm totally gonna use your "I'm a man" technique before the H news if I decide to date in the future!
