I think I see what OP is getting at. What if we used the work “kink” or term “a thing for”, does everyone have their something that pushes their buttons?
I’d generally define it as something that has an unusual amount of weight in your sexual preference. It’s not just a practical need, it’s something that’s amplified for that person.
Some people have a thing for tall partners or short partners, big parts or small parts, clothing or situations. I think everyone (who’s sexual) has something they can’t necessarily explain or consciously control that turns them on.
It’s usually called a fetish when it’s far enough out of the norm, but if someone says they like big boobs, or tall men, everyone just considers that normal.
To answer the question, yes, I think everyone has something. Most consider their “thing” normal though.
