Interesting that you said you are a HD woman and have that same tendency as Geek's W. I couldn't say so..as that is not my label.
I think that for those who are married for a long time that there can be cycles to a marriage. Boredom is one of them. But I also think that when couples "grow through" the boredom that is when M gets good! Because if you get past that stage...each one is basically thinking of how they can give to the other one. At least the marriages that are happy and not just surviving. We are not living in that place, yet, but we've gone there some.
Interesting that even a HD woman faces some of the same issues. Wow! How honest...
So, Geek yours is not an isolated thing...neither are you flawed in your approach....some of us women just keep moving the hoops...
