Boyfriend rarely wants to have sex

So a couple months ago my bf and I started doing long distance. He had to move about 2 hours away from me and everything has been okay except for the sex. We have been with each other for a year and some months. Before he moved the sex was more frequent but still not as much as I wanted. I thought that moving would increase his sexual desires since we would be only be seeing each other every other week, but it really hasn’t. We just spent a week with each other and he barely touched me. I tried to initiate something by kissing him and he just asked if I had been drinking ( I had a sip of alcohol). I’ve talked to him about this before because it makes me feel insecure that he isn’t interested in me physically. He made me feel like the bad guy because it ended with an argument and I had to leave the next morning. Essentially though, he told me I should pursue him more but how do I pursue him when anytime I do he makes comments like the one I previously mentioned. We are both in our early twenties and workout frequently. I haven’t gained any weight so it’s not like I’m not taking care of myself. There are no past traumas that he is expressed to me, and he is incredibly loyal. I don’t really know what to do because it’s been really difficult but I don’t want to seem like I’m sex crazed, just lacking some intimacy/passion.
