It's hard to find an honest person, and you, sir (or ma'am), is that person. I want to shake your hand and proclaim how proud I am of you, and how you accept being proud about it. We need people like you in the world.
As for the topic, it is embarrassing, but it's a serious issue. It doesn't hurt to talk about it, but if it gets too out of hand or uncomfortable, it's best to avoid it. Talks with parents or trusting adults are the best sources. That's where I got my beliefs, and have seen it happen myself. I can honestly state my beliefs true. It's up to the people to accept them or not, and I just let it be.
Once again, good for you! You are the person you wanted to be, and you will defend that willingly and proudly. I salute you.
