Maybe. Do bear in mind that physical problems may prevent a woman from desiring a husband whom she truly does love. After childbirth and/or after menopause, sex can become quite painful, and the medication used to improve this situation has side effects like heart attack, stroke, and cancer. It's hard to force yourself to have sex when it hurts like mad and even causes damage to delicate tissues. It's harder still to choose to inflect potential death on yourself for the sake of having sex. I have seen many, many medical records and have heard from many patients that they are frustrated, they're unhappy, they know their husbands may leave them, but a prior history of cardiac problems or cancer precludes using hormones to fix the sexual pain. This is far more common than you'd think.
Why, in more civilized times, men over 40 usually had a second, younger wife if he could afford it.
There's more than one way to keep a guy sexually happy.
