There’s nothing wrong with social nudity, as long as you take care about which body parts touch what. Doesn’t matter whether you’re conventionally attractive or not. I know several people here in Eugene, OR who doff their clothes as soon as the front door shuts behind them.
What the ####? who in the hell is proud to be naked for a picture with your child and grandchild in it? I am sure the kid will burn the photo if found. If you want to walk around your house naked then that’s your choice—it’s not appropriate when your family is there,especially letting it be photographed.
