Sex at 24

Okay, this is awkward for me. As it may be for other women on this app...however, i have been with my boyfriend for 2 years. As it usually is in the beginning of a relationship, sex was not hard to come by (no pun intended). It has been close to a month since I have had sex with him. While we were on vacation, there wasn't a single bit of intimacy. No cuddling, hardly any kissing, and of course no sex. I was hoping for this vacation to be at least a little bit romantic, maybe he would start something. But no, nothing,nada. And when we are home, it's Netflix and or him or I doing some sort of house work. We don't have children, not really a lot of friends that either of us hang out with. I'm moved 2 hours away from home (to a new state) and I just feel like everything is changing...is it me? Is he not sexually attracted to me? How do I bring up the topic that I want more sex...or feel beautiful and loved and romanced by him more? Am I asking a lot? He does so much for me. I work really hard at my job...I just want him to initiate SOMETHING! Even sex. Does this make sense? I feel as if I am rambling...ugh I just need to talk.
