Should I stay or should I go?

My boyfriend and I have been together for almost 9 months & we hardly ever have sex. It’s been two months since we last had sex & I’m concerned. Our sex life has been kind of off. It’s hard for me to get turned on & sometimes I feel like he just isn’t into it. It makes me insecure like do I smell? Am I too hairy? Like idk. We don’t even say I love you to each other. Shouldn’t we be at that point 9 months in? It’s getting to the point to where I’m day dreaming about other guys. It’s hard because he is like my best friend & I enjoy spending time with him. He supports me & he’s the first guy that I’ve ever been 110% myself with. Plus my family loves him. I never get hit on so it’s not like I’m going to cheat on him. I just don’t know if our sex life will ever get better. 🤷🏽‍♀️ should I stay with him to see if it gets better or should I leave?
