My personal experience confirms the article's conclusions.
When I read the salacious titles for Cosmo in the check out line, I say to myself "there must be an awful lot of unsatisfied women out there." If being single and sexually active were so great, there wouldn't be such a need for these articles.
My personal experience confirms everything in the article as well. A mis-spent youth (very mis-spent), followed by years of suffering, then a godly marriage that I did not and do not deserve.
Many who lived the type of life I lived have not fared so well.
Sexual misconduct has been the ruin of many lives, not just the ones who chose the misconduct, but their children and relatives. It's really amazing that more people do not see this, and think of promiscuity as modern, liberating, natural, and a source of happiness.
Sex without loving, lifelong commitment is one of the most miserable experiences a human being can have. It may have (and doesn't even always have) a superficial glitter, but it leaves the heart dry, lonely, burning-cold, and bitter.
