Hi there, and welcome to scarleteen!
Lots of people going through puberty have that feeling of wishing the fun things like orgasm and satisfaction from masturbation would hurry up and happen already!
But experiences of puberty, and pelasure vary a lot, and it can take time time for the changes in your body to occur that make you more sensitive to sexual pleasure at the same as understanding and importantly becoming familiar with what feels good for you as an individual takes time too.
It's great that you've been able to try lots of 'combinations' as you say, but it can also be good to relax and stop trying too much if it's not resulting in anything pleasurable.
Instead you can spend time with the things you do enjoy and just notice new feelings and body sensations when they happen accidentally.
You might notice patterns: My guess is that over time things will become more clear!

Don't see why they call it lonesome.
I'm never lonesome when I go there." Connie Converse - Talkin' Like You
