Hello, my boyfriend and I are in a monogamous long distance relationship. He has herpes, and to prevent me from getting it, takes acyclovir before and during the periods we visit each other. Unfortunatley, this past Sunday (before he started acyclovir again) he had an outbreak. He promtly took the medicine (4 pills each day since) and never developed blisters. He describes it as a bit of redness which is fading. I am going to see him in two days. Is he contagious? Should we have sex or wait?
