Is lap dancing required in a relationship?

I've been told guys LOVE it when girls dance for them, but I never have before and I'm scared too. I don't feel like I am beautiful enough. But I also don't want to be the crazy cat lady living alone. Why is it required by some guys? (Or girls) ?

A girl told me another reason why they probably want dancing is due to cultural or religious beliefs ( I respect that) I just would not want to embarrass myself.
