I've never planned on coming out to my parents until I moved out, but my best friend told me I should do it sometime soon. I really do agree with her. I'm not 100% sure if they'll accept me or if they'll just kick me out. Should I come out, and if so how, or should I just wait?
Have you considered dropping hints? Like, you may comment about something you saw on the news about the LGBT community (or about a LGBT celebrity). Or, if you watch TV with them, you can comment something about how that woman on TV looks good. You can start from here and analyze their answers, if you don't feel ready to come out directly.
