How do I tell my parents I'm biual?

my girlfriend and I have been together for seven months and she still hasn't told her parents. well, last week she finally got around to telling her dad and he said to just act like she never told him. most parents will keep you from staying at friends houses. I would keep it to myself until I moved out. but this is your decision. you need to think of how they react and if you really want them to know. just tell them when you're ready.
