What things are ok by your societal norm to be open about?

I was wondering what people feel it is ok to be completely transparent about in your life. Are you comfortable with knowing others sexual preference, marital status (to include open marriage of that is one’s choice), religious affliations, political views (even on the contrversial topics). Obviously there are things that we consider to be “rights” but I am wondering where the comfort level lies. What do you want to tell others about yourself and you don’t want others to tell you about them?
