How do I tell my GF to take advantage of me?

Essentially the title.

However, the long version is. My gf is easily the best sex I have ever had. I love our dynamic, and we have discovered many new kinks together. We have sex all the time, and she is the only woman I have ever met who has a higher sex drive than I do while also being incredibly kinky and satisfying. Mostly I assume a more dominant role,; and she takes a submissive one, this is totally fine 90% of the time!

,
The only drawback is that I am the only one initiating. My prior relationship left me with some things that I emotionally flinch at when it comes to sex. The main one is that it is a chore for the other person involved.

I have explained this to my GF a couple of times and she tells me she will do her best, but still no starting things.

Furthermore, every once in a while, I want to be the one who feels used. It feels very nice to be desired and lusted after in a feral way and I would love for that to happen every so often.

Has any other couple had this issue and found tips or tricks to help out?
