>She has a super high drive

You might see an overall improvement by matching it.

It's simple to have a sexual dynamic and still treat someone with respect.

>Once she broke down crying because she thought I was upset that she didn't want to have sex one day

That seems a little 'more' than 'just' a random breakdown, a lot of people will try to emotionally manipulate you in certain ways.

Maybe she simply has a higher drive and wants more?

My GF enjoys sending shower snaps, they're nice to look at and she feels sexy taking them. They're not a required thing and I don't explicitly ask for them but it's a positive dynamic.
