Women: State the real reason why a woman would not want to have sex with her husband?

I think initially women are driven by the hormones. We live to please our men and although we enjoy the sex we are easily excited and aroused by the chemicals in our bodies. As time passes, they fade and sex becomes more work. All of a sudden we start thinking more about ourselves, and about the technique (or lack of). Now they have to work to get you to the same place. Men have no concept of foreplay. What used to take 2 mins now takes 25. Many times we as women don't know why we aren't in the mood anymore. We wish we were. It's the way our bodies were designed. I love my husband to death, but sex ain't all that. It can be frustrating. I feel like I tell him things he just doesn't listen to. It's usually all about what he wants, not me. Even with an orgasm that doesn't make it great for women.
