Feeling bad for being less kinky

I am a fairly kinky person as is(BDSM, rope play, pet play, non con, pegging). But my boyfriend is into more than that (orgies, being on display, has threesome fantasies). I cant help but feel extreme guilt for not being as kinky as him in that regard. And I tell myself it's ridiculous that I have boundaries and such and that I should just be as kinky as he is.. we've talked about it multiple times but I still feel terrible thinking about it.
