I can't accept my sexuality?

Im gay and I have a boyfriend. But I'm terrified to show affection in public. I see all these gay couples that are okay with it but I'm scared of getting looks from other people. And I hear about all those hate crimes and I don't want to be another victim. it even has me questioning my sexuality. I have feelings for guys and girls but I don't know if im gay or bi. Girls don't really turn me on but I find them attractive. Can somebody give me some advice about how to not care what others think and just be myself and how to figure myself out.
