Feel like he’s not attracted to me anymore

So I’ve been with my man for 4 almost 5 years now and everything’s really good I think we are both fairly happy with the relationship. I feel like he’s not as into me sexually as he used to be or maybe I’m more sexual than he is. We still don’t have a place to be intimate as we would like but when we do have moments to ourselves I feel more excited about it than he does. He doesn’t look at me or lust over me as much anymore. I love dirty talking with him and he gives me back the same few responses. Should I not express that side of me as much to see if he initiates more. Is it that he expects it. I really don’t know what to think and it’s making me feel undesirable. What should I do?
