My wife is excatly like this. She uses the excuse that she is a teacher and one of her students might see (in public). I have not kissed her in at least 5 years. These ladies want PARTNERS in life, they do not want LOVERS, and that is something that makes absolutely no sense. I have never been able to figure out why LD's like this want so little out of life, being partners is a very LOW form of relationship. My guess is that she is not only very unhappy with your relationship, but the real driving factors are that she is very unhappy with herself, that her body is NOT doing the things she wants it too.
