When my wife and I were first together we'd be nude a lot when the kids weren't around. We agreed to always sleep nude together. That lasted about a year, then it was back to her old Tshirt-Boxer ways. Now 20 years later we've only slept nude once 2 years ago. She wanted a beach vacation and I said as long as you sleep nude we'll go. We slept nude the first night, but after that the remaining nights were back to the same ole.
Sorry. Maybe raise the thermostat on the AC? Haven't slept with any kind of clothing on at all since sleeping in the car on a trip.
