I have genital herpes hsv-1.
Knowing what I know now, I would date someone with herpes. I have dated men who have had hpv too.
However, when I was younger I would probably not have dated someone with herpes, not unless I was in love with them. Having said that, I did have a boyfriend who I knew had oral herpes, and I knew I could get genital herpes from that, but I thought I was invincible and it wouldn't happen to me. Another boyfriend let it drop several months into the relationship, once we were having unprotected sex, that he had given his previous girlfriend genital warts so knew he was a carrier, though he had never had symptoms himself. I didn't walk away, because I was emotionally involved with him. By that time, it didn't matter.
I was 19 when my sister caught herpes. To be honest, at that age, I thought she was damaged goods and her dating life was over.
Now, nearer 30, I am old enough to see people come with lots of flaws - herpes is just one of them. I would accept a man with hsv-2 - which I could still catch - or something else now. That is partly to do with having seen herpes from the other side, and partly just growing up.
Like most people, before I got herpes I was very ignorant about it. I just attched a stigma too it like lots of people do, I didn't know anything about it at all, I just knew it was a bad thing to have. I thought someone with it either was promiscuous themselves, or was unfortunate enough to have a 'dirty' partner.
Like you I have been pleasantly surprised by how accepting a lot of people are. From what I gather from the people I have told, they all have different reasons for being ok with it. Some have come into contact with someone with herpes before, or have had another std themselves such as warts, or had a partner who has. They are more inclined to be accepting. Some have oral herpes, and are sufficiently clued up to realise the genital version is no different. Some reckon they won't catch it and still want to get laid. Some just take you seriously as a person, and are prepared to accept your herpes because they like you and want a relationship with you. As for my friends, some know herpes = cold sores and some have known other friends get herpes. Those who have a better understanding of what it is accept it better, because they are less likely to be blinded by the stigma.
I don't think I've ever met two people who have had the same reasons for accepting it.
