bf comfortable with me but I'm not with him??

i love my boyfriend no doubt about it.we have been together for 4 years. i can walk around naked and he will always compliment me and what not. i can stuff my face with him lol. but i realized i just don't call him babe. and if i do its only in text. i don't sing or dance in front of him. but he dances and sings all the time with me. any other ladies like this? just been crossing my mind alot lately.
