Boyfriend doesn’t call me hot

So I’ve been having this problem for a while lately and I’ve talked to him about it three times now. We’re both in college but at home for the semester and he comes over about twice a week (and we get freaky one or both of those times). The problem is when he’s home he never calls me sexy or says he wants to see me naked. We FaceTime everyday but he never wants to do anything and he doesn’t even say he’s horny over text. I’m confused because I’ve talked to him three times now and he says he doesn’t realize he’s not saying it but he does think about me. He says he thinks sex and stuff but he never says it? He never says it though??? I prompt him all the time and ask him if he wants to do “sexy time” over FaceTime but he always has a reason not to. We have an ACTIVE sex life but once I’m not physically there he doesn’t want to see me or do anything. Frustrated, any advice would help.
