Life after lust – the appeal of sexless marriage | Life and style | The Guardian: "Everyone – sigh – knows the drill: schedule it in; push through the repulsion/exhaustion/irritation barrier; engage in some roleplay; use it or lose it. But after one's broken the novelty shower-cap rule (I've got a cow and a frog one, you?), after one has spent 15-20 years cohabiting with the same perfectly delightful, perfectly attractive person, seeing them walk nude around the house about five million times, it can feel, frankly, a little … inappropriate.
