Does the mood of guys in bed by age of 30's+ diminished? In what way and why?

I am a newly wed, I am wondering why my partner and I we're not physically connected. I started to feel bad and to feel not in a mood also making doo with him because I am thinking that there is no space for me in many ways because he have many conditions. It also often happen that if I wanted he want me the one to do it because he saying that he is tired. So I don't feel to have it and knowing that he will just finish always first before me. I seldom meets my needs in bed, I mean my . What is the best way to do because I am started to think that my man has another fantasties, women or impotent man. And it's really annoying
