Were you really "never" sexually attracted to her? I doubt it. I think it's more likely that you were attracted to her at the beginning (does a man ever really marry a woman he's not sexually attracted to unless maybe he's under the influence of drugs or alcohol at the time?) Come on...honestly...she turned you on in the beginning, didn't she?
But what probably happened is you found out about her "hard time with sex." Of course she's going to lose her attractiveness if she doesn't like sex. One of the most important requirements in order for a woman to be sexually attractive is to be open to sex with YOU and obviously attracted to YOU. Right? Right. And if she isn't, she might as well be your sister or your mom.
Definitely, this is not going to go away without communication. You ultimately are going to have to have a heart to heart talk with her about how important sex is to you...and the fact that it's bothering you so much. I wouldn't go so far as to tell her you were "never sexually attracted to her" (because even I don't believe that's true, and I don't even know you)...or even that you don't find her sexually attractive now. But you definitely need to let her know that you're bothered by this, and that it's more than a matter of simply being frustrated by not being able to get your rocks off. You need to let her know that you have a need that only she can fill and that not even all the masturbation in the world could ever replace.
