How to please submissive GF?

So my gf is more of the submissive type that’s not afraid to make the first move. I’m more ln the middle cause I just enjoy sex overall and making sure she is satisfied but In our relationship lm the “dominant” one. She has always been more sexually conservative cause of her upbringing but has made progress in getting past that. My question is what can I do to please her more / better?

For example I know she loves compliments during sex but besides some general stuff, ldk what to say. She loves being chocked, smacked on the ass from time to time, I spanked her once or twice cause she just decided to lay across my lap randomly with her butt up ln the air so l got the message, and one time I spit in her mouth ln the moment. All things she wouldn’t admit or would shy away from ln a day to day conversation then she will get flustered / embarrassed that she enjoyed it lol.

I’m just looking to do more to please her submissive side so lf anyone has any tips or can point me in the right direction that would very much be appreciated. Or if anyone can tell me how to be more dominant that would probably be best lol.

It’s late where I’m at so lf I don’t reply soon then I’ll get back to you tmr
