I actually took the description to be a description of pretty much what most women do all the time (or at least dating/early M) cast in male terms. Indeed, I thought that was the point of the illustration -- to demonstrate how male-sexual-satisfaction centered most sex is by role reversal, and how much women do to in terms of romance and attentiveness to male sexual needs.
How abou that, lol.
If it is a genuine description, then I agree with others, it is unbalanced and doesn't sound like too great a sex life for the guy. But it still works to show why women who start out playing that role while dating/early marriage tire of it.
At least the guy gets to O with his partner rather than in private later, lol, as is the case with many women dating/early M.
