unfortunately you've been given erroneous information

odds are you have had symptoms of herpes and just didn't realize that they were what they were. most folks are able to start recognizing the signs of recurrences over time. sometimes it is redness and itching, not always obvious blisters that hurt a lot. you do not have to have obvious lesions present for the virus to be actively shedding.
you do need to talk to potential partners about your herpes. If you don't and they contract hsv2 from you, they have the right to sue you and it' s just not worth it. it's also just the "nice" thing to do. You know you are infected, you know it's contagious and it's part of the whole "talk" we all should be having with potential partners - std's, testing, condom use and birth control.
On average, a male partner has a 4% risk each year of contracting hsv2 from you if all you do is avoid sex anytime you have anything going on genitally. If you take daily suppressive therapy, the risk is cut in half. throw in condoms on top of that and a male partner has a 1% risk each year on average of contracting hsv2 from you. very low risk with minimal precautions but you still need to talk about your herpes. Trust me when I say if you think it's hard bringing it up before you are intimate, it's even harder to talk about a few weeks/months into things. Most partners appreciate the honesty when told prior to sex, talk about it after you've been intimate and for many folks that's a trust issue for them understandably.
I highly recommend the free herpes handbook at
www.westoverheights.com . also Terri Warren's book "the good news about the bad news" is available for under $15 on amazon. It goes into far more details than her free handbook and really covers the psychological side of things more. Both are terrific!
