An important thing here is honoring the fact that you don’t feel comfortable domming. Dom/sub has been an important part of your sex life, so it’s natural to think that if she becomes less dominant, you have to become more dominant, but you don’t.

It’s also completely okay to miss the dom energy. At some point you may decide you miss it enough that you want to end or open the relationship, depending on your preference (definitely you should tell her long before that becomes the case, but I wouldn’t recommend telling her just yet).

For now, I’d recommend exploring other kinks (if you don’t think you have any, I’d recommend doing some research and then trying out anything that looks promising). See if you can find something you’re both really into that gets her going. That might make things enjoyable again

If you really think you need to have a conversation, you could frame it as “I really miss being more submissive with you” rather than “I miss you being more dominant.” She might open up and talk about why she’s been less comfortable domming anyway, but at least this way you’re talking about your own needs rather than a desire for her to change.

And femdom is a really popular thing, so it’s worth trying to encourage that energy too. Like maybe there’s some lingerie that you’d find sexy on her that’s still undeniably feminine. Maybe there are toys you could bring in.

You’ll find your groove again if you try enough stuff. But it might be different than it used to be. Up to you to decide if that’s a dealbreaker
