My boyfriend doesn’t want sex

My boyfriend and I have been having sex for a while. But lately it seems like he doesn’t want to have sex with me anymore. He still likes blowjobs and whatnot, but I have to ask him explicitly to return the favor and when I try to initiate sex he tells me he’s not in the mood. And when we DO have sex, I don’t feel like we’re really connecting the way I want us to. It doesn’t really feel intimate even when I ask him to look me in the eyes. We do have moments of intimacy here and there outside of our sex life but I don’t know how to make those translate to the bedroom. Maybe he would want sex more if that part of it got better. I don’t know. Thoughts?
