This article boldly asserts that sleep is the new sex.
It pertains mainly to the difficulty couples have finding time for sex post-children, but I think we've all (maybe) chosen sleep over nookie at some point. And not for reasons relating to a partner's unattractiveness or body odor. Sometimes, you really are genuinely tired, right?
Then again, some couples maintain that they're always in the mood.
Would you be offended if partner chose sleep over your sexual advances? Does how long you've been in the relationship make a difference?
