My wife has suffered from cold sores all of her adult life. We've been very careful for about 18 years, until recently. I don't believe she has ever had her cold sores tested to see what level her cold sore is, but she believes it's herpes 1. My question is, yesterday we engaged in oral sex and afterward she noticed a small bump on her lip (the beginning stage, no blisters), but today the white blister is there. Is there a chance she may have transmitted the disease to me? and if so, what can I do to remedy it?
