Then don't wear tight underwear......LOL :D :D

Seriously, I sleep naked because it is comfortable. The only problem I have, outside of laying on my stuff, is someone knocking on my door awakening me from a deep sleep. I have a tendency to just jump up and go answer the door. Neighbors, friends and even strangers have been flashed more than once.

When I lived at home it was embarrassing when my Mom would come into my room unannounced to make sure I was awake. Morning wood was hard to conceal.
