As I posted on my thread - I have a similar problem as you. The responses to you also prompt me to act in the safe and respectful way suggested.
One of the praises of (even a bad ) wives - is Matzilatu min HaCheyt. They save Husband from sin. These bits of advice, highlight the fact that not only by partaking of the heter of intimicay with my wife, I have a a lessened desire for sin, Pat beSalo, But a much higher level of Chomas Nashim Bonta Baisa - A wise women builds her home.
Her innate wisdom, which you so cleverly described is the tool HaShem gave her to help her husband.
Ultimately, this is a test of my relationship with my wife. This is a hard test. Especially regarding sexual issues, and especially since I feel impure, and wrong. I am afraid she'll "find out" so how can we even really communicate clearly? The static on my side of the line will be appparent.
Maybe when she realizes how much I care for her, and am willing to "bother" myself so that she won't get hurt, and to protect her - she will reciprocate by willingly wanting to share in the burden. The wife of Abba Chilkiya the great Tzaddik - would go out to meet him on the edge of town, taking care to dress up to find favor in his eyes, so that he wouldn't Chas vShalom think about any other women.
Halevay my wife would dress up for me, every day when I come home!
I don't mean to blame her or any wife for my problem, rather to show that the relationship is lacking. If I take all the energy that I "invested" in P*** and living a double life, and poured it into our relationship - WOW would my wife feel loved.
If I would look and gaze at her, pondering her every beautiful quality - like the song Eishes Chayil does, one letter after another - would she feel cherished?
Could I invest in beholding my woman's beauty for hours and hours on end? I know I can
I will try this Shabbos eve...
