" When sex was only available within marriage, people recognised that this led people to marry for the wrong reasons: to obtain something that was artificially restricted in society as a whole. Sexual liberation was intended to allow people to have a clearer head when choosing who they really wanted to be with. But the process remains only half-finished. Only when we make sure that being single can be potentially as secure, warm and fulfilling as being in a couple will we know that people are choosing to pair up for the right reasons. It’s time to liberate ‘companionship’ from the shackles of coupledom, and make it as widely and as easily available as sexual liberators wanted sex to be. "
