I sleep naked... except for the few (occasional) nights of the year when the furnace can't keep the house up to 60 degrees F, so I wear pj's... or if I'm running a fever. Then, there are exceptions to that too. Even if it's REALLY COLD, if hubby is sleeping with me, we can keep each other warm very nicely. Of course, if I'm sick, I don't want sex anyway.

If it's really hot, I'll sleep naked without a sheet! I'm likely to turn a fan to blow over me at times like that.
