I'm 27, been with my girlfriend for 2 years, and she's NEVER ORGASMED!?!?!

So, I'll make this as concise and brief as possible, but you must know I'm at my wits end here. I'm thinking of leaving my girlfriend because of this issue and some others in our relationship. How interconnected they are is a difficult thing to decode, but...

My girlfriend and I were friends for several years before we started dating. Our personalities and perceptions of each other were clearly different then. She was 6 years deep in a MOSTLY long-distance relationship. Where I was 4 years deep in a bachelor pleasure fest. She had only had 1 or or 2 partners. I, over 20. Her boyfriend broke up with her, potentially because of the continued long distance and her career ambitions that made them living in the same city hard, but he ended it by saying he no longer loved her. I had learned the error of my wiles and had spent a year in siberia (not literally) maturing, returned to the city to find her single. We immediately hit it off! And, quickly made our intentions known. Courted each other for 2 months before finally having sex for the first time. I was really excited! I respected this woman. She's brilliant. Sharp. Witty. Hilarious. Ambitious. Everything I was looking for in a partner.
It had been 8 months since she had sex so things were slow going... But that was okay. I was really into this girl. 6 months into dating and we exchanged "I LOVE YOU"s. I felt it! And, I still do. MORE THAN EVER! I LOVE THIS GIRL! But, there are serious sexual issues. She had only climaxed once... (forgive the title, for keywords sake)
She doesn't masturbate and is bedeviled by the fact that I do? I find this puritanical, incredibly simple minded and uninformed. We've come to loggerheads over this and I honestly can't believe a modern, intelligent woman hasn't taken ownership of her own sexuality. She is fixated on the fact that I might be thinking about someone other than her during my own private sexual experiences... So, she clearly has control issues, too. I've told her that I'm not going to stop masturbating, that it's a healthy part of my sexual life. I don't over masturbate, maybe every other day, at that.
She won't give me blowjobs. I've received maybe 10 in our 2 years. She hates the smell of ***, and hates it in her mouth. I've never ejaculated in her mouth. This really frustrated me. But, wasn't a deal breaker at all. I voiced that I would like more head on several occasions, in polite non-jokey ways. I told her it was something I enjoyed and would like more of. Still nothing... But, honestly I can live without. It wasn't that big of a deal.
The kicker... The last orgasm I remember her having was over a year ago. I *** every time. For her, I have tried everything. I've read all the other similar posts on this site, and several others, and after talking to my closest friends... Romantic foreplay, sexual foreplay, asking her to be vocal, massaging, varied/attentive/soft/hard oral stimulation, her on top, different positions, encouraging masturbation, both private and together, manual and penal g-spot attention, mentioned toys - out of the question,... I am attentive, but not over bearing, and that's been confirmed by her. I addressed all of these things to her directly, indirectly, in a healthy a way as I knew how. Voiced my concern, saying I needed her help, saying and meaning that it wasn't my pride, it was me wanting to please her, fully, taking our relationship to the next level, fully realizing it. THEN giving her months of room to implement, without me looming over her shoulder (so to speak). I wanted her to own this, so she could grow at her own speed. I knew this all had to be organic, but still the problem persisted AND she's completely NON VERBAL about it. I have to bring it up. She WILL NOT TELL ME WHAT PLEASES HER IN BED. Tight lipped (forgive the pun). She's claimed that I'm too focused on the sex of it all. So, I've spent the last 8 months really focusing on her emotional needs. We got to and exposed some core trust issues on her part and some behavioral issues on mine. We identified them and agreed to work on them. I feel like I'm carrying my weight in that department, but it's becoming hard NOT to resent her. I feel like I've done right by myself on several occasions, bringing it up when I had to, and have been responsive to her needs. I mentioned going to see someone and she scoffed. She is not friendly to therapists given a tenuous past with them. Also, giving her space so she didn't have this hanging over her. But, how can it not?! Orgasms either happen or they don't. Still, we pushed on. She has never been able to explain to me why she can't orgasm. I haven't explicitly asked her about her orgasms before me, maybe I should. I'm lost... Here's my working conclusion. Please tell me what you think.

I love her. VERY MUCH. I think we have very different sexual pasts and needs. I'm a little more tapped into my nervous system than her. I think spending her entire college years in a long distance relationship, with very limited and brief sexual encounters, stunted her sexual growth, but excelerated her emotional intelligence, which sadly is now being used against her. I believe a mutually healthy and enjoyable sex life is one of the cornerstones of a relationship, not THE cornerstone, but one of them. Without it, we can't take the next step, move in together, etc. If she can't orgasm because of emotional issues, I find that unacceptable... I have made myself more than available emotionally, proven myself to be someone worth her trust, worth her feeling comfortable around, I take that very seriously, and if that's still the case then I fear she needs to find someone else who can support her more, that I need to find someone else. If she can't orgasm for biological/physical reasons, then she needs to suck it up and go see a specialist with me or by herself if that makes her more comfortable. She doesn't talk to ANYONE about sex. Not even her best friend. She is completely opperrating in a vacuum, her own thoughts just amplified over time. And, NO, she has not been sexually abused, by her own admission. I really believe she needs to take control of her sexual life, find someone to talk to, if it's a friend, fine, if it's a therapist great. But, she must feel so alone and trapped with this problem, something I'm not able to help her with, and not for trying. If she won't find someone to talk to then I take that as a sign that she's not as serious about this relationship as I am, and I will need to move on.
I might add that we are both very busy career people, working very high-stress jobs that take up a lot of time. That can sometimes make things hard, but it's also something we love about each other. I wouldn't change that at all.

Thoughts? Questions? Concerns? I've put a lot of thought into this, but it's not all here so please ask questions if you're confused or think I'm glossing over something.
