While there is a chance of HSV1 from oral sex, if the yeast cream helped, chances are it’s that. The cream might not be enough. I would ask for something stronger. See about getting some diflucan. A few treatments might be needed. Do you have any odd discharge? Do you shave down below? If yes...refrain from shaving and just trim the area. I understand people like to shave but the skin is delicate, shaving is basically trauma to that sensitive skin. If hsv is a continued concern, test 12 weeks from your last exposure with an IgG test. And I am not the morality police but use condoms. You’ll be okay!
