Agree with everyone who says talk to a doctor. I did that when I was dating my ex with herpes. Unfortunately there is no "cure" for it, and anything that claims to be a cure is a swindle. But my ex did take Valtrex, and my doctor said that taking something like that does help lessen the risk of what she called "viral shedding," which is how the disease spreads to other people. If he doesn't already take a disease management drug like Valtrex it may be worth looking into.
