Daddy Dom

So me and my boyfriend are into a fetish "lifestyle" called daddy dom. There is a lot more to what I will say, and it different for each person. Basically, I will act like a little girl and he is my caregiver. I call him daddy and he spanks me and stuff like that. Outside of specific fetish groups, I've never known anyone who has been into it. Thoughts?
​Also: if you're going to be rude, don't comment. I know incest is wrong, it's not a father thing, it's just a caregiver thing.
