cozyp828, it's possible that your wife feels shame about her lack of being "womanly" towards you, but won't admit to it, and therefore doesn't want to discuss it. That possibility might give you some ideas about how to approach the problem.
It's helped my relationship, though not yet solved the sexual problem, by telling my wife that I don't think there is anything "wrong" with not wanting sex. Plenty of people are like that and they are fine. And, likewise, there is nothing wrong with desiring lots of sex. The only problem is when two people are so different in their desire for sex with each other.
"it's possible that your wife feels shame about her lack of being "womanly" towards you" - we always think its us, but it may be the way they feel about themself.
I've heard about a man whose sex life opened up after his wife got into physical fitness. IE: he wasn't getting it, and started to once she got into shape and on a gym kick.
So for those of you who have tried everything, this may be another stone to observe.
Plus being in good physical condition improves the flow of hormones and the such.
