One of the booby-traps of modern relationships is the unquestioned assumption that two (or more…) people who love each other and live together will sleep together. In reality, as you point out, many people will have happier relationships if they acknowledge that this part of the Hollywood cliché is as realistic as everything else churned out by that cesspit of misinformation. It is perfectly possible to have a harmonious and loving relationship without sharing the same bed for sleep each night. And frankly, how much nicer to be woken by a frisky lover who’s had a good unbroken night’s sleep than to attempt to drag oneself to consciousness after yet another night of can’t-sleep torment?
