Have you expressed how truly important this is to u? Sex is about so mug more than just sex. Maybe she thinks that u are just looking for more action. I guess what I am trying to say is maybe u can tell her how important it is for u to be close with her and share that intimacy. I mean, if u agree with that, lol.

Have u thought of going to a counselor together? Is she going thro menapause or recently have a baby? Sometimes that can affect a woman's libido.
