<human>: I'm an 18m and my female SO (little less than 1.5 years my younger) seems really against moving forward physically. 

Let me preface what I mean by saying that at my age, I'm given conflicting advice: that if I'm not physically happy I should break up with her, and contrarily that if I do break up with her for physical reasons I'm a douche. 

This is really confusing for me. My girlfriend and I have a pretty great relationship in all other aspects than physically. We enjoy our time together, get along well and communicate pretty well, too. We like being around each other, have similar hobbies and do stuff together often. The problem comes when I try to be intimate. I say I because she's really not a participant. She seems really unsure of her sexuality. She won't initiate physical stuff readily and always says stop before we even get anywhere. I'm not even talking penetration. I don't have a problem waiting until she's comfortable to do these things. The thing is, it's been 6 months since we have made any progress. I'm frustrated and am torn between feeling like I'm pissing away my teenage years and feeling like a dick for wanting something better. 

I've been in multiple relationships before now where this wasn't a problem. There was a natural progression to things in the bedroom. I've given this stagnation so much time because I do care for her. 

I've confronted her about it before but unlike other things she gives vague answers and gets really frazzled. 

I know that at first glance the obvious answer should be just to move on, but I'm at a bit of an impasse because I truly value her company and the memories we share.

Can you provide a brief overview of the text?
<bot>: I'm confused about whether it's okay to break up for physical reasons as a teenager and torn because I really like her as person. She's a good girlfriend, but not a good lover.
