I have a girl and two boys. They know about gay people and all that that entails. They know they are different, and they don’t hate them. None of them are gay, or are going to change their sexual orientation because I explained to them about gay people.
My eldest son is EXTREMELY aware of the opposite sex. I have noticed this since he was two, when he was looking at a picture of a girl in a bikini and said ” I LOVE B**Bies!” HE WAS BORN THAT WAY.
