Especially when it comes from their husband. The man they pledged a life to. The man who they said vows with. The man of their dreams. You.
It won't work you say - so when have you run from a challenge before? - that is a cop out and an excuse ... you can find a way to make your wife comfortable enough to want to be your bed mate - it just may take some time to woo her 
Most often we lose ourselves in the moment and it takes being present to create the possibility for a renewed sex drive in a marriage ... you can't be resigned to the fact that she won't get turned on but rather open to the possibility that you don't know how to turn her on any more ...
The modality and methodology I incorporate are not a quick fix. You have to find patience. Be willing to work hard for the reward.
I have a few clients turned civilian to prove my theory. We started as provider and hobbyist(enjoying nasty and naughty playtimes) then morphed into sex therapist and client(taught him how to do it to his wife). But I can seriously say I helped create a safe zone in their marriage where their sex life evolved and is amazing. I also get thank yous from the wives, a very humbling gift.
I have even coached other girlfriends in how to get the most out of their sensual interactions in the hobby - making them better 'providers' in their own words.
It really just takes a man with the Balls to try it for it to work.
But I guess the payoff for not trying is better than trying with the possibility of failure, to those whom have not tried.
The real question behind it all isn't 'if she is willing to change' but rather 'if you are willing to be the man that turns her on' ....
If we take responsibility for our own actions then we create the opportunities for the things we want most in life and have results to show for it. By being(behaving) the way we want our life to be, we become successful. If we take the steps that put us in the path of our wants - we will get them!
But if you always do what you always have done, you will always get what you have always gotten.
I want you all - wives and SO included- to have the best and biggest O's imaginable!!
Love, hugs and smooches,
Chloe

Chloe,
I love what you are trying to do and I am also sure I am not alone with that view. I do believe it is very common for long-term relationships to fall into ruts of bad habits and resentment that decay much of the happiness that was there at the start. It's really ironic that in our society you need a license to drive a car or practice a trade, but we essentially get no formal training on how to be a great lover, partner in a relationship, or parent. I also believe there are preconceptions and fears that hold us back from our potential for happiness and growth.
But, personal change has to start from the desire. I don't want to blame! But, I don't believe most wives have that desire to change - especially in the way you want. If you ever read the comments section from a Kim Kardashian story, the meanest and most judging comments always come from other women. How many providers out there feel like they can tell friends outside the industry what they do, let alone family? Our culture just does not accept it - especially other women. In fact, they have done studies that one of the biggest fears of a women is being labeled an outcast. And I think most wives do not have the courage to head down this path that could have them branded by their peers.
I do believe there are women and couples that this could be an amazing opportunity for growth. I certainly wish I was one of them. But, unfortunately my guess is that the couples that need your help the least (are the most open-minded, communicative, passionate) would probably be the most interested in pursuing and not vice-versa.
I hope this isn't discouraging and you use it more just as another opinion for your "research." I think anyone who has been a successful entrepreneur has faced many critics telling them it could not be done, the market is saturated, and no one will buy it. Instead dream big. Create change and the world you want. Life is short!
