Denomination: Queer. Humanist.
Prayer: No. Got nothing from it for years and used to think I was doing it wrong.
I think of Denomination as something mutable, so I'm a little surprised to see you list a sexual orientation as part of a denomination.
You may well have been doing it wrong. Personally, I view prayer as a means of asking God to help oneself achieve the best, and or give em thanks. Anything even remotely similar to prosperity gospel type prayer would be wrong in my opinion.
It's more of just a 'subheading' tbh. I think my queerness and humanism is 'active' that is distinct enough from just passive non-belief.
I've felt disconnected from prayer from 5 to 25. Same with confession and communion. It was just a ritual that I used to existentially worry I was getting it wrong while everyone else was doing it right because it always felt hollow.
