Don't know what to think/feel/do 😖

So my husband got some news today. This is gonna be a little choppy please bear with me...... He's always had a high sex drive. So he's always masturbated a lot. From time to time he would notice what he thought were friction burns. I guess the last time it was bothering him more than usual so he went and saw the doc......not friction burns. Freaking all the way out right now. Apparently according to the nurse he spoke to my chance of having it is pretty low. I just don't know what to do with myself like my head is just spinning. He's pointed them out to me before and they really did look like friction burns but obviously I'm just questioning whether this is something I've been noticing the whole time or not.....I don't know what to do. I love my husband. I don't want to leave him (he was sure I would). But this just fucks my whole world up ya know. I've been breastfeeding our daughter so now I have to get her checked out too.....I need someone to help put my mind at ease 😟

Edit: told you I'm messed up...... It's fucking herpes
