I agree that wearing clothes to bed when you have a HD spouse is extremely frustrating. I guess the LD spouse is concerned that sleeping nude may just be an unwelcome invitation to the HD spouse that he/she is more available for sexual advances. However, I could also see how sleeping nude could be simply a comfort issue in some cases and be exclusive from any HD/LD dynamics. In your case and mine, both of our partners started off sleeping nude and then changed for one reason or another (i.e. concern of kids, poor body image, etc.).
