Should I do this for my boyfriend?

I've been dating my boyfriend for just about six months now. His b-day is just two days away and he told me one of the things he wants is a b-day and I told him that would be fine. But then he told me he wants me to do it really hard and make it hurt and to use a belt. He told me has a thing for gettin ed and wants a really hard b-day in to remember his birthday by. I could totally give him a play one but I don't know about the real thing. He told me he wants me to whoop his azz big time. Would you all do this for your boyfriend if he asked you to? I do care about him and I am sure it was not easy to confess this to me I just don't know about going through with it and going to town on him with a belt so I am still thinking about it.
