Yeah, my wife and i are very open with each other about kinks and desires even and especially if we don't share something. Sometimes it's a thing the other person is willing to try, sometimes it's not.
I've also been fairly insistent on checking if our close adult friends are interested in talking about sex or desire. An innocuous question here or there to gauge temperature, and drop it if it goes nowhere.
Between mutual friends and my online friends i think i have 5-10 people i could about various kinds of kink, fetish, or sex with pn a semi regular basis.
Other people's desires are fascinating to me and i didn't get any sex ed from home so i chat with friends.
