I do think a lot of it is fairly subjective though. What might be a turn on for some is not for others.
Two examples - my friend is really into the hard fast strokes, flat on her back, doesn’t move as this makes her orgasm quickly and she is always after “harder and faster”.
I like this only after a slow build up... but I like other things too.
My ex liked to be handled quickly and roughly when I was using my hands- I’d got it down to a fine art but would have to swap hands every minute or so as it was tiring.
I broke up with him and my next boyfriend after could have written your thread I reckon - practically everything I did he didn’t like. I was stroking too fast, he didn’t like the whole length just the head, etc etc...
(He steered me very gently but I could see what he was doing so we had a frank discussion - it’s worth noting that he was an incredible lover from my point of view).
I listened to what he said and tailored it to him.
I think as long as there is a tonne of communication, this situation can be “bettered” in some way.
Just on the flip side of that though (be careful what you wish for) I said to my most recent ex that I like dirty talk ...
We were in the middle of some fairly vanilla sex and he just suddenly went “yeah I bet you love that don’t you, you ... you.... beast” 
Beast though.
Good luck op
