Maybe a lighthearted question this, but how important to a relationship is what we wear, or don't wear, in bed?
For me sleeping naked with my wife has always been one of the best things. And it's not primarily to do with sex, although clearly it's very handy for that when the mood takes. But even if "rumpy pumpy" is not on the cards it's lovely to have skin on skin contact going to sleep or waking up.
My wife does occasionally really enjoy wearing her PJs (and I've got a pair at the bottom of a drawer for really cold nights) but for the vast majority of our marriage we've been sleeping au natural and it's something I've realised that - for me at least - is a really, really important part of closeness and intimacy. Something I'd miss at quite an emotional level if my wife for some reason insisted on covering up all the time at bedtime.
But everyone is different I guess?
