"You can become stuck in your own dramas of sex and money. What you can't live as openness, offered without residue, creates stickiness in your life. Yet the price of discovering your tar of unfinished business, your sexual and financial traumas and fears, may exceed what you are willing to wager. Are you willing to face, feel, confess, and open beyond your every sexual and financial fear and complication, now? Human birth is for those who are not quite ready but may be on the verge—that's why you are here as you are."
Maybe you can glean more of a sense of where he is coming from here.
I just also want to add that I doubt very highly that you desire your wife as much as you just desire sex. You seem to think pretty lowly of her and have so much resentment that you're probably cornered your self into needing her desire, because your too afraid to admit that your the one who has no desire for her.
Let me repeat you are the low desire spouse, you don't truly desire your wife you just want to get off.
