From Psychology Today comes an article with an unusual (at least in contemporary America) premise: The best way to have healthy, happy, sexually fulfilling relationships is to learn to be an individual. From the article:
Becoming an authentic adult means going against the whole drift of the culture. It specifically means, among other things, soothing your own bad feelings without the help of another, pursuing your own goals, and standing on your own two feet. Most people associate such skills with singlehood. But Schnarch finds that marriage can’t succeed unless we claim our sense of self in the presence of another. The resulting growth turns right around and fuels the marriage, enabling passionate sex. And it pays wide-ranging dividends in domains from friendship to creativity to work.
