I don't think it's intentional false advertising. Early on in a new relationship the woman really does have a higher drive. The phenomenon is called limerance. Whether she likes it or not though, internal wiring for women tappers libido down over time. As I mentioned after 24 months, they may have no spontaneous desire at all. This is particularly true after kids. The really strange thing is that the same woman with zero spontaneous desire for her husband could have enormous desire for another man. Limerance restarts her drive. How many times have you seen this with recently divorced women who wouldn't touch their husbands but after the divorce wind up jumping on every cowboy they can find. Once she starts another long-term relationship again though the clock starts and she's got 24 months before shes back in the low drive state again.

Anyway, a better approach in my mind is to be aware the phenomena exists and to put in the work necessary to keep your marriage as healthy as possible. How do you do that?

1. Get your butt to the gym and stay in shape. Keep your hygiene up to.
2. Get out of the house. A little absence makes the heart grow fonder.
3. Set a solid positive tone in your marriage. Be a leader, and don't be a Eyore who says no to everything.
4. Be interesting. Have some fun hobbies. Be the man your wife proudly points out at a party and says that guy, he's my husband. Nobody wants to be married to an uninteresting couch potato.
5. Get your wife away from the dang kids from time to time. Date nights/vacations etc...
6. Don't watch too much porn.
7. Don't let your wife get bored.

Have you tried rereading and applying this?
