JWs influenced the sex life of our marriage in different ways (no "perversions", etc) but I never resembled the husband in the OP. Rather, I would try to convince my (ex) wife to get in the mood, so that she would initiate it. If I would initiate, that was a turn-off for her, so I rarely initiated.
Of course, my current marriage to an ExJW does not have any of these hangups, so that part of my life is so much better!
