SOS Please help

So I'm Fernanda and I'm bisexual. I really want to come out to my parents but I'm scared because one day when my dad, my sister, and me were in our car and we were listening to the radio. The radio host said that this girl thought her boyfriend was bisexual and was cheating on her. And after he said that my dad said,"That guy likes girls and boys......ewww." So now I'm scared about telling my parents (specifically my dad) about being bi. But I'm not so scared about telling my mom because she has guy friend that is gay. What should I do? Please leave a comment if you have any advice that can help me.
