Why does seem like the only thing my boyfriend cares about is sex?

He pretends to care about more than that but it doesn’t seem genuine, like he pretends to care about other things to hide the fact that he’s most concerned about sex. He will call my phone at 3-4am asking me to meet him on public transportation, which isn’t safe at all in our city and with me being a woman and the first thing he does when I touch down is something sexual. When his car was running he would wake me up at that time as well knowing I have just gotten off just hours prior to him calling me, telling me to pack clothes and be ready. He rarely ever came and got me at a reasonable time and when he did, for example one time he came and got me in the afternoon but he couldn’t even wait until we were out of traffic before he unzipped his pants while driving and asked for oral. He didn’t ask me had I ate, how my day was etc he waits until after I do things like that for him to think about asking those things.
