I have known people who were bare at home the majority of the time; yet never referred to themselves as a N or http://nudist-video.net . 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 involvement and commitment to the nudist philosophy.
I don’t believe you need bother with defining or labeling your nude tendencies – unless you are actively seeking beach fucking . But if you still wish to define what you do, I believe the term “household-nudist” is appropriate to your circumstances. As far as your last question, it depends on your intention. Should you get a kick out of the notion of other people seeing your wife nude, then you certainly may be venturing into hedonistic territory. I appreciated my X being openly nude amongst other nudists; because her comfort with nudity was significant to me.
As well as the acknowledgement of her attractivenes provided me with some measure of pride. But it had little to do with some hedonistic impulse to exhibit my naked wife (p.s. I’m not judging you at all; simply describing te difference).
