Update: Our FLR has evolved to ass worship being the only thing we do. Seeking perspective on dynamic shift.

This is an update to my previous post:

So we had a talk, she said ass worship is just her main preference, so ever since starting the FLR and centering her pleasure she naturally gravitated toward what satisfies her most. She likes the other stuff we do because I like it, so she finds pleasure in my enjoyment, but rimming is her personal favorite. Oral feels "just okay" to her, fine but not even close to as satisfying. And if she chooses, she would always rather choose we do something revolving around her ass, I agreed before to free use regarding to oral and rimming, and it turned out she just enjoys her ass worshipped the most.

In the end, she said she’d pay more attention to adding variety. I’m glad she was honest, and I want to make it most pleasurable for her but I’m also kinda bummed. It sounds like everything else we did was mostly for me, not really for her own pleasure so It makes me feel less enthusiastic about those acts now.

Am I being ungrateful? How do others manage those differences, and how do you handle knowing your favorite acts aren't necessarily your partners?
