Why wear clothes in your own home?
Since I belong to several nudist groups I hear many stories from members who've asked this. The responses are usually the same and fall into three general groups:
1/4 says they can't and follows it up with actual reasons. Then you can see the wheels turning as they try to figure out if they get some textile-free time.
1/4 says something to the effect of, "You know, I never thought of it that way. I guess I could, at least some of the time"
1/2 appears scandalized/horrified as if you suggested they jerk off in the middle of the street or something equally ridiculous. Then they say they can't but never actually provide any reasons no matter how long they go on about how they 'can't'.
Personally, unless there's some reason not to, my clothes come off shortly after I'm in for the evening and getting dressed is usually one of the lasts things I do before leaving in the morning.
