Hey, wait a minute. I'm a woman and I don't just assume the guy is a helpless clod re the house and the children. That may be true, indeed the likeliness bears consideration, but we don't know that.
My own guess, perhaps as off the wall, is that the intimacy and sexual rapport may not have been well developed before the children came along - the joy, the relief, the exquisiteness, the wildness, the quietness - sometimes, indeed often, this takes time, and that now there is no delight in thinking of that which was, for Spouse.
I don't assume husband is any more out of it re intimacy and sexuality than is the wife.
She may well be more tired, but I don't personally know that, or know of any of their barriers to intimacy.
A lot of the lecturing is fairly presumptive (however correct the presumption is or is not, not that I don't ever do that lecturing business).
