MoJo said: No problem. It's really too bad that I can't just come over and have a threesome with some of you guys and your wives. Some things are better taught by demonstration.-JK, JK, JK.
Threesome might be a little over the top IMHO. Maybe a book with some pictures and steamy two-part novel that had average sounding/descriptive women, that wanted her average sounding/descriptive common sounding man to make love to her but he wouldn't, would be a good start.
The book would have to portray how she felt neglected, and how the lack of a satisfying sexual life influenced her satisfaction-with-life level.
The second part would have the genders reversed. Similar story.
On the last page, have the two people married to each other.
MoJo, with your knowledge of books, or someone else, I am sure you/they could cut and paste two stories together to come up with a book to demonstrate how living in a SSM effects R's and people.
As far as affecting and causing any significant change to the LD partner, that is another hypothesis/can of worms.
About dating??
Are their any dating sites where people rate the dates/people they had?
