Unfairness in the bedroom?

My so and I have been together for four years and have a child together. I love to please him and I DO. I dont mind giving a bj if he asks /wants one...but he verrrry rarely goes down on me. I no overweight. Im clean and fresh all the time...I dont get it. I mean I dont actually like to suck dick. I like to know I can make him feel good. Ive mentioned this to him multiple times, obviously...to no avail...any.advice??? T.I.A.
