You ought to call his bluff and start walking around naked, too. Tell your dad you'll need to stay because nudists have so few options.

He may have always had Naturist tendencies but got tired of waiting. You never stated your age which would give us a better indication of situation. Good luck!

I would try talking to him about a rent or lease arrangement while you get yourself on your feet. I get wanting adult children to get there own place, but he should be able to come to some sort of win/win situation given the current housing market in North America (assuming you are in NA) my area is looking at studios starting at 1250 plus utilities for a paint peeler. it's why I rent rooms in my house to family, helps pay the mortgage and cost them 1/2 "fair market" and they can save faster.

You can try that too. He’ll probably stop.

What is the big deal of being nude? Is nude body really that creepy and perverted to people? I don't wear clothes at home, unless entertaining guests. I don't react to naked bodies, I grew up knowing that naked body everyone has one. In a family or community sauna, or unisex dressing rooms were a standard. People who reacted in a room of young children were removed by older men. I don't remember ever been embarrassed even though I was overweight. Funnily I was abused fully dressed by a man who I had never seen naked and neither had I ever been naked in the country we were. My dad was nude constantly, same as brothers and sisters. Mum loved covering up. Either compromise, discuss rent agreement or learn to understand " home is a place where you are not critiqued, yelled at, punished or disrespected for being yourself" unless he is inappropriate towards you I don't see how his nakedness directly impacts you. Do you feel unsafe? If so report otherwise he is in his own right to do what he likes in his own house considering you're an adult you also have same rights when deciding your life and when you have your own place you do your rules. Yes I lived with my parents, step parent and my boyfriend. Nothing special of nude body

Join him.....

Report your dad to the police for sexually exposing himself to you (same sex still wrong), ask for a restraining order....daddy will have to find a place to live in the meantime. Regardless of relative or not no one can expose themselves to others even if it is in their own house.
