Turn ons?

I have had sex with several guys and hooked up with a handful of others, from all those encounters I have learned my biggest turn on is being able to distract my SO through their turn ons, kissing necks and collars, scratching backs, playing with hair, felling up thighs, etc. My current boyfriend seems uninterested or effected by all of it, I’ve tried asking what turns him on and he either dodges the question or says something useless like “you”. I’m just getting frustrated and curious if you guys have any advise on different turn ons?
