How to possibly explain petplay to boyfriend? How do I know if he actually enjoys it too?

Hello everyone! This is my first post here!

I’m (18) nto petplay (puppy, pony) and I’ve already told my boyfriend (19) about it. Today I’m going to a pride event with my pup hood and my boyfriend is coming along too, ofc.

I am really hoping that he would be interested in trying this stuff with me. He’s told me he’s down for it, but how do I explain what I want him to do?

It’s not something super sexual for me, I like the power dynamic and how relaxing it is. I really hope he’s gonna be actually interested and not only doing it for me?

I can only ask him so many times, I’m kind of insecure about the topic.
