Alone, I hardly ever go to sleep naked. I tend to just get flustered very easily. I usually wear relaxed chemises or my OH's baggy t-shirts.
With him, I'm usually wearing sexy short chemises or sleeping naked with him. It's weird how comfortable I am with him rather than when I am alone.
The new Seven Til Midnight chemises and dressing gowns are amazing! Enough comfort and sexiness to keep you both happy. I just ordered the cherry print one! =]
The OH prefers nothing! Just plain nakedness. >.<
