I keep no secret of my clothing choices, all neighbors within sight know and see me most days. Kids know, one prefers me clothed, one lives here with other half. Some grandkids know some don't because of possible custody issues. One grandkid and family stayed here for a while when she move back to this state.
I live in Oregon where it's legal to be nude in public except for a few cities. It's pretty accepting here here but not quite enough for my taste, like downtown areas. So with that in mind I only go nude on my property, but I don't try to hide if neighbors are out or when cars drive by.
My wife is a full blown textile but fully accepts my proclivity. She's the one that informed our kids that I would be nude always when she talked to me about them moving in, they agreed after a few seconds. The rest is as they say, history. I don't believe that something that is such a big part of my should be kept secret.
