Yes, very. My body is far from perfect. But I live in America: Land of the free, home of the seriously obese. So. Having taken far better care of my body than many others, and honestly not giving much care to the appraisals (or lack thereof ) of others, I'm quite at ease being nude.
This changes if I am nude and the others around are uncomfortable with the nudity of others.
I had a nightmare the other night. A close friend is in the Coast Guard. he's been to sea for a few months. His apartment is a two-hour drive from mine, but he's asked me to drop by and air it out, stock his fridge, and stay a few days so it feels lived in when he gets to port. The day he is to arrive, I am showering and pretty much just waiting for him to get home. I've forgotten my towel in the loft bed. I've left my clothes there as well, expecting to be all nakies 'til the last possible moment. I come out of the bathroom, and slam into his father, who's decided to surprise him and have a father-son bonding experience. His father is surprised, wet, angry, embarrassed, and very, very uncomfortable. I read all of this in his facial and body language as he turns away. He demands to know who I am, and refuses to say another word to me until I dress. He doesn't say that, but I know he won't say another word. I am annoyed. I stand stock still trying to decide whether or not to let his discomfort force me into wearing my clothes and forgoing my nakies time.
I told my friend about the dream, and he said we should just hope nothing like that happens if he asks me to do such a favor. His parents are very fundementalist. They would be very upset to encounter a woman intimate enough with him to be walking around his apartment naked, with or without him.
