It's obvious to me now why the so-called European-style mistress works for some people, especially when both partners have deep ties to family and in-laws that they don't want to change. Yes, I certainly know it's more than just the sex. But at times, and thinking only on the surface, it seems utterly absurd to completely change virtually everything -- house, family, in-laws, financial obligations, etc. -- just so you can have sex for a few hours a week in a manner which other people would "approve of", as if it were any of their business in the first place.
ssmguy - I HAD the so called European-style mistress (we were both American). It felt great at first, seemed like the perfect solution. But you know what, it was a sham. The longer it went on the more wrong it felt. YES it was thrilling, YES the sex was great. It was still only half a life.
