Yesterday my boyfriend and I got involved in some sexual activity while I had a scabbed cold sore right under my lip (not directly on it). To get more specific (sorry but it's needed), the only thing I did was touch the top of the penis with my tongue and lightly sucked on his testicles. The cold sore itself was scabbed over and never touched his skin or any openings or cuts. Right before the ordeal I also cleaned my lip area and the scabbed area with alcohol. What are the chances/probability he will get HSV1 on his genitals?
