It was vaginal oral sex. Okay, thank you so much. I really appreciate it.
if you haven't had sex then its most likely not herpes; did your bf give you oral anal? if not its probably not HSV 1, besides the fact that it doesn't take a month for a herpes bump to become a blister it usually will evolve in a few days into a blister. this could be anything such as an ingrown hair or something else. if you are concerned of it see a dermatologist.
