Why women loses appetite for sex

I wanted to find out and answer to following question. I’m married for already 5 years and now I’m 26 years old. Before and some time after we got married we had sex almost every day.

Now it’s once in a week at the best, and my wife always tries to talk her way out saying that she’s tired etc. I just wanted to find out what could be a reason for this, why does women lose their interest in sex? Maybe it’s me?

Best wishes, Mr. I.
