Sooner:

I must be married to your wife's sister - zero interest in any physical contact, especially sex. The occasional peck on the forehead is as good as it gets. Hostility abounds whenever the subject of sex is even hinted at and severely punished for mentioning the topic. I sympathize with you - the situation is really devestating to your whole outlook and perspective on life.

Anyway, have tried everything over the past 5 years, everything from being the most attentive person possible, long exotic vacations, weekends away etc. etc. I have also tried the distant, low attention and numerous other routes without success. In fact the low attention route results in an even frostier environment. I have tried going for councelling but she won't go as I have "the problem".
I guess like many things, "drastic times require drastic measures". I feel like I am in drastic times and the only scenario that is likely to work if I want to change the situation is to threaten divorse and be prepared to carry this out. Other options, which I reject, would include finding another willing partner or taking medical measures to reduce the sex drive. I would be interested in any other comments and have just posted a thread on this topic.

I hope there are some better answers out there.
