I know how you feel. You're new with this. I don't have any great words of wisdom other than look at the facts and explore WHY you feel the way you do.
I wasn't a big player over the course of my life. I've had a few adventures, but nothing compared to most. And honestly, I feel the same way you do. When I'm propositioned now (even though I know I wouldn't take them up on it anyway), it hurts me because I feel like I "have" to reject them (otherwise have the disclosure talk or lie to them and myself which is completely uncool). I'd rather reject someone (sorry if this sounds harsh) because I think they're not worth it - rather than because of a condition that I have. So, in that sense, I TOTALLY feel your pain.
It's going to come down to healing (for both of us) - whether it's emotional or physical - or both.
On the social/stigmatized societal aspect of all of this, we've been taught that people with herpes are dirty and diseased. We're taught that only slutty girls (or guys) get these things, and nice girls and guys don't. (We know that this is NOT true)
From a medical standpoint, it's more common than most disorders. It's an easily transmitted condition (like the common cold, mononucleosis, or influenza - although transmitted differently). And, just like chicken pox (also a herpes virus), CMV (cytomegalovirus), and Epstein-Barr virus (mono) - it stays with you forever. (All of this is true)
However you need to think and feel about this, however you need to spin it - it's time to spin it that way. If you decide not to have sex, or not to "play" (and I'm SURE that there are couples and groups that are H+ that would love to have another member), then that's what you need to do. As long as you do it with your eyes and your heart open, that's all that matters.
