Your teenage son thinks he is bisexual?

So believe him. Take him seriously. Tell him immediately that you love and accept him exactly as he is. Don't try and talk him out of it or change him.

It was nothing you did. It's nobody's fault. He didn't choose this. It's not a choice. Some people are naturally gay or bisexual. It's normal for them to be this way.
