A childhood belief about sex

Okay so this is more about sexuality in general than any particular part of sex. I am and always have been a bisexual and when I was little I thought everyone was. I thought it was really a common thing. That we could all have crushes on both genders but there was some kind of secret deal that society had made, that we'd all keep those feelings of love and attraction for same sex a secret because it didn't make babies. I thought everyone just ignored their feelings for people of the same gender because we all wanted to have kids when we were older. But I didn't mind the idea of not having kids so I told a girl I liked her. She told everyone and they made fun of me, but that only encouraged the theory that they were all hiding the same thing and they were just mad that I wasn't following their rules. Because of this, and the fact that I was bullied so much for it, I decided I would follow those rules and I pushed all those feelings I had for girls deep down inside. It wasn't until I was eighteen that I finally came out of the closet and accepted my feelings for same sex. To this day, I still feel embarrassed when I find myself attracted to a beautiful woman.
