<human>: Can you summarize the given text in a few sentences?

We're both 21 and we've been together for about a year. 

My boyfriend is wonderful. He respects me, claims that he loves me, treats me right, takes care of me, etc...But he's the type of person who is not at all affectionate. He RARELY initiates a kiss, a hug, sex, etc...And while I'm not clingy or needy for attention or affection, it hurts me so much when I reach out to him and he rejects me. Last night I reached out to touch his arm and he withdrew it like I've got all kinds of STDs on my hand. Even though he asked me to stay over afterwards and we had sex, his reaction to me reaching for even a small amount of affection from him hurts me deeply. We broke up once before because he thought that I liked him more than he like me, so since we've been back together I've been very conscious about reaching out to him for any kind of affection. That's why I'm talking to you guys and not to him right now, I'm afraid that if I ask him to be more affectionate towards me, he'll think that I like him more than he likes me.

Now, before you guys tell me to dump him because of our incompatibility (I know, I know, I've read this advice many times before), I would like to know how I should feel about this rather than what to do with him. My emotion's all fighting each other and it'd be nice to have other people's input. Even though he is nice to me, does his behavior means that he's probably just not into me or he is just a very anti-affection person? Should I love him for who he is? How can I communicate with him to make this whole situation better?
<bot>: BF (21) doesn't show me (F21) any affection and sometimes even rejects my touches. How should I feel about this?
