I went to a naturist camp and it felt uncomfortable to be dressed, when everyone else was naked. In the company of naked/semi-dressed swingers, I'd be comfortable-ish being nude, although I prefer skimpy lingerie to no clothes. I no longer wander round the house naked as my older sons are teenagers and I know they'd be embarrassed which would transfer to me. It took a number of years for me to be comfortable in my own skin with my husband, let alone strangers, and even now I have occasional body-image crises. The only time I have felt truly oblivious to my unclothed state was each time I was in labour, but then I guess I had other things on my mind.
