Tmi bedroom help

My husband and I have only been married since October. However the last three months he and I haven't had much sex. I have tried so many time and for the first time yesterday he went soft on me. And then it happened again tonight! Wtf do I do?!? I'm so angry and sad all at the same time. I can't have a marriage without sex. Like we don't even have a kid yet why is this happening?!? HELP!
