If she keeps shifting the reason, chances are it is just an excuse because she may not really know why she doesn't desire you, she just doesn't. If that is the case, then maybe it does fall more squarely on you and how much masculinity you exhibit. Again, JHMO
If she truly does have ALL of those "LD" issues, then a combination of medical, psychiatric, counseling is the only shot you have. If she refuses, then you need to decide can you live with no desire or do you need to cut and run (figuratively).
But I have this sinking suspicion that if you act in an unambiguous masculine way for a long enough period of time that she can trust that behavior will continue, her LD-ness will slowly disappear along with the excuses.
