I strongly disagree with your view that relationships shouldn't involve sex. Sex is natural, sex is health, and sex is a great way to share the most intimate bond with the one that you love. Making each other feel that good is an incredible way to show that two people love each other. Sure, some sex is casual and done only for lust, but having sex with the person that you love isn't wrong in any way, gay or straight. Love today is much more real than it was 50 years ago. Today, young people, for the most part, marry who they actually love. Years ago, marriages were much more often for economic reasons, or political reasons. Now, people love and marry whom they wish, regardless of their parents' opinion on the matter. In this sense, love is more real now than it ever was.
