I have a FWB who unfortunately contracted Herpes about a year ago. We have not had sex since long before he caught it so I'm okay. I got tested as soon as he told me and I'm clean. His condition has calmed down a lot now and apparently he gets a small (like 2-3 blisters) flare up approx once every 2 months or so. Google is unhelpful, some sites say no definitely not, no more sex ever again and some say it's fine as long as you DTD during a quiet period when there are no blisters. Apparently condoms do not stop you from catching it because it affects the pubic region and not just the genitals.
How risky is it to have sex with him when he's not having a flare up? Obviously I absolutely won't if there's even the smallest risk but I just thought I'd do some research. I'll be a bit gutted if I can never DTD with him again because he was the best shag I've ever had :o but obviously my health comes first!
