Since you forgot to write it, I'll fill in.

Many women lose interest in sex after they have children. This can be very hard on the husband. Many women even make the choice that they will love their children, but do not have enough love to give their husband. It is incredibly painful for the man. Admittedly, in terms of biology this makes some sense and fits into what sociobiology describes for mammals, she got what she needed, but it is no less hard on the husband.

There, that matches the title.
