I assumed from that that he meant he expected oral sex or some other all-for-him interaction, because that's just my perception of him. Your mileage may vary of course.
Funny -- my take on that sentence was that he was trying to preach to men not to expect to get laid just because there is some kissing or touching before dinner, but in the meantime she did the dishes, the homework and the laundry and now is too pooped. I didn't infer that other meaning at all, strictly speaking about the writing.
I don’t think of a hug or kiss as a “sexual encounter.” I hug and kiss my children, parents, some friends (mainly the Hispanic ones, especially the elderly) in a socially appropriate way.
I did say my interpretation was colored by my overall impression of Mr. Prager, whom I’ve never liked, as a “personality” expressed in his writing. I don’t have the idea that Mr. Prager would think it acceptable that although a wife might be feeling positively about her husband at 5:30, after cooking, dishes, laundry, cleaning, dog threw up, kids flooded the bathroom, mother-in-law called, Girl Scouts crisis, a few false labor pains ... at 10:30 she’s “too tired.” His urges are her job, period.
As I said way back, words fail me as I attempt to convey how happy I am not to married to this guy.
