Feeling Different From My Partner

I'm a software engineer and my partner doesn't share the same kink as me. Lately, I've been really into roleplay that involves some power dynamics, but she's more about affectionate cuddling and open communication. It feels like there's this gap between us, where I want to explore these boundaries, and she wants everything to be clear and safe. Tonight we tried something new, but it just didn't feel right for her. I'm left wondering if my desires are normal or if they're a dealbreaker in our relationship. Anyone else ever struggle with feeling like your kinks don't match up?
