Sex after 1 year

Do you feel like your SO is still interested in sex? My man is awesome and I know he loves me, but I don't get that feeling like I'm turning him on anymore. Like he doesn't look at me like he used to. And when we go out he doesn't come home and tear my clothes off. He's sweet, like he strokes my hair and will talk to ms about anything. But he doesn't call me beautiful anymore. When I ask him about it he says he doesn't pay attention to my looks - that's not why he's with me. And I love that, but at the same time it feels like something is missing. Am I being superficial? Is this normal after dating someone for a year? 
I am a good looking woman, I take care of my appearance and I am fit. So I know it's not because I am unappealing - I just wonder if I am unappealing to him. When I ask him he seems confused and tells me he will try to compliment me more. But that's not what I want. I want him to want to have sex with me. I almost feel like he's bored or something. Thoughts???
