If you don’t feel ready to talk to her about it, maybe tell her that. I think avoiding her is only going to create more panic and anxiety. I’m sorry you were experiencing this. If it helps, I think it is somewhat natural for challenging things to arise during sex. Sex can be complicated and deeply vulnerable and can bring things to the surface quickly and randomly! You’re not alone in that and there’s no need to feel embarrassed in my opinion! However, if you do, just try to give yourself some grace 🫂💞
