If Dennis Prager is married (his recent whining and carping about sex-on-demand for men makes one wonder about his marital status) I really feel sorry for his wife. But that remains for her to sort out with him. If he's married. Still.
For the sake of balance, DAMMIT JANET! will provide married men (yeah, you too Dennis, if it applies) with some advice about getting women "in the mood".
Do housework. Serious housework. Cheerfully. Efficiently. Diligently. Every week. Not as a reward for sex, but as an enticement.
Nothing gets a woman in the mood faster than watching a man sweat over a kitchen floor, getting it squeaky clean.
Finally, avoid marrying one of those ProWomanProLife gals. Their advice to women, regarding married sex is probably that women should "Close your eyes and think of England". One of them supports the notion that only casual sex is pleasurable sex. I really feel sorry for her husband.
