Being comfortable in your skin

When the door knocks. Answer the door naked? or only when you know who it is. You go over to a friends house. are you comfortable to just strip and sit down? If your like me.... If i see a man , especially hairy one. I get horny, do you refrain, or do you immediatley let the man know you want sex with him? what is the etiquette for being nude? I am very sexual
