Is it safe to shave even if you have genital herpe?

Probably not: Genital herpes cause enough pain. Wait until the blisters are gone. Hitting a herpes blister with a rasor will really be painful.

Shavnig & HSV: You know, if you cut yourself while shaving, it is theoretically possible to innoculate some virus into an open cut and get a new sore. Overall, however, this doesn't matter. The skin infection with HSV will go away on its own, and the infections in the skin are not what we really worry about. The big worry is about possible spread to an infant in childbirth.
