No sex in over a week!!!

So me and my boyfriend haven’t had sex for a week now... maybe a little over a week. When I go to lay down for bed he doesn’t come to bed anymore with me now he doesn’t come in till hours after I have gone to sleep. Every time I tell him I want to have sex he says later but we never end up doing it. It feels like he doesn’t want to have sex with me anymore like ever... like I don’t turn him on or something. And when we do have sex and he’s on top instead of looking at me he looks all around the room and I don’t know why. Even when I’m on top I try to ride him and he has his hands on my side and then flings his arms down and has a huge ass sign like I’m doing something wrong. But then other times he acts like it’s the best sex ever and he’s cums hella fast or talks dirty during it. But I feel like I want sex a lot more than he does. Like he never wants to when I want it but when he wants it ( which isn’t that often) we have to or else he will get pissed off. What came I do to make him more turned on? What are some positions we can do? Or what can I do before we have sex to get him really turned on?
