COG, it's okay to be discouraged, and to want more from a marriage than what you're getting. I know you've said that you'd put up with no sex for the rest of your life, but would you really? I mean, really? What kind of marriage is that? Unless that's what you really want, which I don't think is the case.
It's not just a matter of satisfying an urge; it's also an emotional need. You are missing out on a large part of a marriage.
You've talked a lot about what you've been doing for your W to make her comfortable, but has she told you what she needs? If not, she needs to think about that and let you know; otherwise, you're working in the dark, and that's not fair.
COG, you've been a huge help and tremendous inspiration to many of us here, and not just because you seem to have had success, but because of who YOU are, because of your faith and your inner strength. You are a good man, and I KNOW that God would want you to have the most fulfilling life possible.
I will be praying for you, Nicola
