Oh the beginning ... just the touch of his hand makes you want to go at it on every surface in your apartment. But soon enough, things settle down and you're content enough to keep it contained to the bedroom. And then, even your pillow-top, memory foam Tempropedic isn't seeing any action. If you're like many women, your relationship is pressing on, but your sex drive seems to be left in the dust. Why does this happen? Are women falling out of love? Or just out of sex? The following are the top three reasons women stop wanting sex, and what you can do to regain your libido.

Problem #1: It was "the spark" that lit your fire.
According to Tammy Nelson, psychotherapist and author of Getting The Sex You Want, as we're falling in love, "we feel an attraction to someone that is primarily directed by brain chemistry. The spike in hormones and an intense release of dopamine, serotonin and adrenalin gives us that in love sensation that's characterized by compulsive thoughts and sexual attraction." In laymen's terms, all those feelings of euphoria and the excitement of a new guy makes you want it - bad. Then, as the initial excitement wears off, and you become more used to the relationship, there's not as much spark to ignite your sex drive.

Solution: While there may be no way to recreate the initial excitement of a new relationship (it's just not the same once you've farted in front of each other), you can recreate the newly dating sex. Have sex in a new place, in a new way, with a new toy, while watching a hot video, or while wearing something sexy. Nelson also suggests sharing your fantasies with each other and veering away from ordinary sex.
