I have known people who were nude at home the majority of the time; yet never referred to themselves as a N or N. My X never referred to herself as a nudist either; even though she participated in social nudism. Those I have known who did call themselves nudists or naturists were active societal nudists, with AANR memberships and resort/club membership. They used either term to “authenticate” their active participation and commitment to the nudist philosophy.
I actually don’t think you need trouble with defining or labeling your naked tendencies – unless http://sexcam4.net are actively seeking a social nudist environment. But if you still feel the need to define what you do, I think the term “household-nudist” is relevant to your circumstances. As far as your last question, it depends upon your intent. If you get a kick out of the concept of other people seeing your wife nude, then you might be venturing into hedonistic territory. I loved my X being openly nude amongst other nudists; because her comfort with http://fairpost.net was significant to me. And the acknowledgement of her attractivenes provided me with some measure of pride. But it had little to do with some hedonistic impulse to display my nude wife (p.s.
I am not judging you at all; merely describing te difference).
