coming out...

I am 12 and identify as bi-sexual. I've only come out to my best friend who is like a brother to me and he is fine with it and also my sister who is 15 and her best friend who is also a good friend of mine. Idk where to start because I'm comfortable with myself but idk about my dad. He has made gay jokes in front of me and I always get upset. But luckily I know my mom will accept me. She is like my best friend I'm so lucky to have her. (Sorry for this little rant)
