My boyfriend has HSV2 but has not had an outbreak in 15 years. Today I started oral sex on his penis when I noticed 2 lesions that were clearly herpes. He agreed. We both took 2 valtrex because we were concerned. I have low white cells so I'm a bit immune compromised. Can I contract HSV2 from putting mouth on new active lesions? We always use condoms for vaginal sex and thought we were being very careful. Also, I have vaginal HSV1 and take valcyclovir daily to minimize shedding.
