How do I help my 12 year old son?

Hello! I think it's likely that my wonderful 12 year old son is gay. He's flamboyant and somewhat effeminate. He likes dancing, musicals, My Little Pony and other things that check the boxes. All good.This week he became upset because a friend saw his My Little Pony drawings. One of the things he said to me that broke my heart was "I hate who I am." He feels the need to hide parts of his personality to his friends. Maybe he's right.I don't know if he suspects he's gay. I don't even know if he is gay for that matter. He is generally a happy kid and he has a lot of love around him, but I'd like to be able to do a better job of helping him with this.My question for you all is what help or advice did you receive when you were younger that helped you come to terms with who you are? It's fun to focus on the brony thing, but that's a symptom. I'd rather hear of things that might help him in the wider sense.Thanks in advance!
