My W has used the "you'd never be satisfied" line on me, but we've never had sex frequently enough to see. I'm pretty sure that when we first M, she was afraid of what saying "YES" to my desire for sex would mean.
As far as HDs ever being satisfied goes, I've told my W that it's obvious that I can live with a lot less than I want and need. Why should she assume that I would be unreasonable if I got more?
