Telling my boyfriend I want him to spank me?

My boyfriend and I have a great sex life. As we've gotten to know each other more it has just gotten better. I'm kind of kinky. He bit me once kind of in the moment and he apologized but I told him I liked it and he could do it more. I grabbed his hand and put it around my throat one time while we were going at it and he got the hint and is totally into doing that now. We were doing it doggy style and he scratched my back and I told him he could do that more if he wanted.
