"My goal is not to punish her (don't throw me in that briar patch!) but to get me to a point where I can live next to a woman indefinitely without having sex. ie, conversion to a sister. But will she see this as rejection even though she has no interest in sex? I am not looking to get her to pull the trigger here. My primary motive is self preservation."
Is this really your goal - is it what you genuinely want, and if so why? You say your motive is self preservation, but if you'll excuse my directness, I would say that's a complete avoidance of your responsibility to yourself. If the cost of a man surviving within a marriage is that he has to permanently quell his desire for his wife, then I would say that that is simply too high a cost. Its completely unnatural and inherently unmasculine.
I mean honestly - what are either of you going to get out of embarking down this arid road?
Its not that I don't have sympathy with your situation, but there are other healthier, more productive, more masculine paradigms to work from than the "In order that my natural sexual desires not make you feel uncomfortable, I will pretend that you are my sister not my wife" one!
If you want to know my perspective on the SSM issue - which I think is part of a much broader tapestry - look through my previous posts (there aren't many!).
Hit me back if you want some more specific ideas, but I can virtually guarantee you that your proposed self-denying approach will end in disaster.
"A man can be destroyed but not defeated" - from The Old Man and the Sea, by Ernest Hemingway.
Which I take to mean that every man has within him a spirit of relentlessness and optimism. Its already there; he just has to cultivate it.
