Female led relationships discussion

I’ve always seen myself as submissive, particularly regarding my sexual needs. After fantasizing about chastity, femdom, and FLR for a long time, it has finally become real. Once my fiancé and I were comfortable with the concept of chastity, I proposed an FLR. She agreed that it made sense alongside chastity and liked feeling more confident and powerful both in and out of bed. We read up on it, discussed guidelines (cleaning, cooking, driving, etc.), and now that it’s actually happening, I’m really struggling with the submissive role. I find myself doing things resentfully and selfishly. I hate this but don’t know how to stop. Does anyone have advice? I truly want this to work out, especially since she has decided she likes it too. Any help is much appreciated.
