Great news! And it is really great you are posting about it. If you can help other men at least question whether they really know their wives sexually, you will be helping a lot of women and marriages.
I don't have time to make a long post, but it all goes back to a lot of women feeling trapped in a false sexuality because they fake Os, don't want to injure the male ego, need to be "good" women, etc... This is not all the fault of the Hs, but the Hs can help A LOT with the problem, as you are finding :-)
