The truth is that the millennials and generation-Xers that are desiring sex without emotional connection are really no different than their parents. The truth is that we have been having sex without emotional connection for centuries. This isn’t new at all.
People have gotten married because they were arranged marriages, they were pregnant, they wanted out of the house, they needed financial security, “peace between the clans”, whatever. Historically, getting married (and the subsequent sex had) without emotional connection really wasn’t that uncommon.
And often, even when there is love and true desire for each other in the beginning, between obligations placed on each other, bad behaviour that drives us apart and poor communication skills, the emotional connection slowly gets eaten away until there is nothing left but a shell of a relationship. At this point, they stay together because of children, financial reasons or because they simply don’t want to be alone.
And some still have sex. Perhaps they do it “like they’ve always done it”. I know some people who only have sex after they’ve had some drinks or gotten high. Others just fantasize about being with other people or doing anything else while doing it.
