What is the best way to tell my family (Specifically Parents) that I'm Biual?

I'm but I haven't told my family. I don't feel like I need to. It's part of who I am but it's not all of me. I feel like who I am in a relationship with is my business. However, if you feel the need to tell them, I think the best way is to sit them down and just say it. Something like "I want to tell you something. It's important to me and I want to share it with you. I would like it if you would listen to everything I have to say before you say anything. I'm biual. It's part of who I am but it's not everything. I wanted to be honest with you so that when I start dating people you will be prepared. I hope that you will accept me the way I am. I love you very much. Thank you for listening to me." Feel free to quote me if you like. Good luck.
