70% of new infections of Genital Herpes come from partner who were unaware of their HSV+ status. I think your 1% stat is about right, usually I see 2% (each year) when on meds and avoiding sex during an outbreak or feel one coming on. The disclaimer for any statistic is that your mileage will vary, it's not a guaranteed percentage for everyone. The obvious is that some people will shed more than others and I'll bet there are some who rarely shed if at all. Turning the numbers around, there's a 98% chance someone won't get infected from you. Pretty good odds in my opinion.
I saw a post once where the woman used Herpes as a 'guy' filter. If they can't be supportive on this issue, then they'll fail on the more important issues. Herpes is not a reason to leave or stay in a relationship.
Some people are willing to take risks, others aren't. If someone (male or female) is just looking for a casual partner but not wanting marriage from this person, they may feel it's not worth the 2-6% risk each year. It depends on whether you'll looking for free milk/bacon without having to buy the cow/pig.
Would you be willing to be involved with someone who's HIV positive? If I was just looking for a summer girlfriend, I'm not sure I'd be willing to take the risk. Sounds shallow huh? However, if I'm looking at this person as a life long partner, then the though process will be a lot different. For one thing, I'd sure wanna be informed on HIV and know all the facts, not just the tabloid news about this virus. Was the guy who rejected you informed about HSV, or was his knowledge only from the rumor mill and late night jokes.
So, don't worry about the ones that reject you, look at it as their loss and their shallowness on this very very common virus.
If for some reason you're thinking of not telling someone next time, don't do it; be truthful and honest. Maybe holding off on sex until the relationships develops a little bit is the better suggestion. Don't give him a reason to leave in the very beginning. Instead, let him discover you, and have that be a reason to stay regardless of this common virus. Besides, chances are pretty good he's already got HSV1 or HSV2.
