Looking for advice about disclosing to family members

I've just started a relationship with someone who has HSV-1, and I have made the clear and deliberate choice to love them without any fears or guilt of contracting it myself. in fact, to be certain my partner isn't constantly worried about asymptomatic infection or feeling guilty about anything, I'm going to basically treat myself as if I have it. With Valentine's Day coming up I want to be able to kiss and be intimate with my partner, so it's a big step forward for our relationship and whatever happens I'm not worried about myself especially. what I need advice on is what I should do about my close/immediate family. I'm hoping to find people who understand this, but my immediate family has a very affectionate traditional way of greeting and saying goodbye which is, we often kiss each other on the mouth. Nothing uncomfortable or beyond platonic, just quick pecks where the corners of our mouths touch. All my French and Polish relatives were immigrants who did the same, so please I ask for no judgement or comments about that being strange or bad. but my dilemma is, if I'm treating myself as if I have HSV1 to be responsible about it, I'm going to have to stop kissing my relatives. My mother in particular will most definitely notice and say something about it. at which point I have no idea how I should respond. I already know it would be irresponsible to lie or hide it, so I don't want to do that. I'm worried that my mother would blame or hold it against my partner, which I'm very much afraid of for multiple reasons. I'm close to my mother and my partner values close family values and wants to be close to her too. I'm also worried that my partner heavily seeks approval from my family and would have a lot of anxiety and guilt from this situation. I have told my partner that there are multiple scenarios where I'd have to tell my family, i.e. if I have visible cold sores, if they notice my avoidance to direct kisses, etc.. but we're both scared about the idea. I'm hoping someone here might be able to share how they handled a similar situation without judgement.
