TITLE: I[22M] have been having a problem with my gf [20F] for almost 10 months now, and we've been together for 11 months
POST: Me and my girlfriend have been together for almost a year (11 months) and I really love her, she's been an amazing girlfriend so far. We've had our issues but it's never been something we couldn't work out. Theres something that's been really been cutting me deep for quite some time and I don't know how to deal with it, thats why I am here. 
      
For the first month and a half that we started dating we were pretty physical and it was amazing. Then she left for two weeks for training (she's in the army) and when she came back she said she doesn't want to be as physical as we were before "because when she was out there she realized she didn't need that." 

Ever since then I've been the one who has to initiate any kind of physical intimacy, and its gotten to the point where I have to be persistant and ask a lot to get anything. I feel like an asshole doing it but to me being physical is really important, not because I am getting satisfied but because I get to share something very personal with the person I love. Thats how its been for the last 9 months. Recently its been getting even worse, I barely ask to do anything with her, (i'll probably say something once a week, and its always a 4 second conversation) and all she says is, "i guess i can give you a handjob." Its like its an obligation to her and she has no interest with me (physically) at all anymore.
   
I don't know what to do, it really hurts me as a man and as a person. So, what do I do? I should make it clear that I'm not here saying, "hey guys help me get laid more." I want to get to the bottom of this, I've tried talking to her about it but all she says is that "it has nothing to do with me." I am out of ideas of how to figure out the cause of this and I need some outside speculations.
TL;DR: 
My gf treats me really well in every area of our relationship, but when it comes down to any type of physical intimacy she shuts down
