than HSV2 in the genital area).
My question is this: if the person I am sexually active with has been exposed to HSV1 already (but they get outbreaks only on their mouth, like cold sores), are they still at risk for contracting genital HSV1 by me? Or, will they only get them around their mouth, and not the genital area, because this was the first place they were exposed to HSV1?
wasn't protected. There doesn't have to be an actual cold sore present for the virus to have been shedding and transmitted to your genital area.
Your partner having hsv1 orally gives them significant protection against contracting hsv1 genitally but not 100%. Still err on the side of caution and when you have genital symptoms, avoid sex but otherwise it shouldn't be an issue. hsv1 genitally on average doesn't reoccur very often either so disruptions to your sex life should be minimal too.
