Is it normal that i find it hard to accept myself for being bisexual?

Up until a few years ago, I've always been straight. Now I'm attracted to men as well as women. I have this huge crush on one of my guy friends and he is always on my mind. I haven't told him that I liked him that way or that I am bisexual. I haven't told many people, including family, that I am bi. I know that people will judge me if I reveal that. I am also afraid that I will make God angry if I date a guy. Is it normal to feel this way?
