How to be more dominant

I'm 44M married to 44F. We don't have sex as often as we'd like, but it's always good when we do. I'm the higher-libido spouse. I wouldn't call myself dominant, but my wife does often tell me she likes when I take charge during sex —little things like when I put her in the position I want or put my dick in her mouth without asking. I've tied her up a few times too.

I want to lean into this more, but it doesn't really come naturally to me. What kind of things can I do to be more assertive/dominant that she might like?
