As for the advice given me about divorce being preferrable, I'm not interested in a new wife, with a new mother-in-law, new step kids, etc., etc. I just want to know what good sex is like. Otherwise I'm happy with my wife.

Changing or splitting up homes, vacation homes, property, kids, responsibility for college educations, and good relations with in-laws, etc., etc. just so dad can see what a little sex is like seems really dumb. And I mean really DUMB. Dumb, dumb, dumb.
