Hello Katie,
Welcome to our little home here. I hope you can have some fun reading and posting.
After saying that, I need to get a little more serious. All the names that you see alot here are people that come here often, and will not have a problem with you going nude. BUT, there are other important people in YOUR life that you haven't told us about. So...
Did you go to the beach alone, with friends, or with family? I ask this because it is VERY important that if you go to this beach, that you be safe. That means talking to your Mom and Dad about it. If they don't know, you need to tell them how you feel about being nude, and about going to the beach. That may suck, but it's for the best, really. Trust me.
Do not go alone. That would be much too risky. If you go with friends, go in a large group, and stay TOGETHER.
I don't want to be a stick in the mud, but it is extremely important that you be as carefull as possible. Don't tell anyone from the beach where you live, and make sure you aren't followed. If you are going to be nude at home, make sure no one can see you. People can get funny ideas in their heads if they see a young girl naked. Again, the best thing to do here is to talk to your parents. They may freak out at first, but they need to know so they can take steps to protect you properly.
If you're parents aren't nudists, you will probably have to do alot of talking to get them to let you be nude at home, but it can happen. We've had several families here that have become nudists because of their children. Don't worry, but talk to Mom and Dad first. Be clear, and be polite. Yoy may have to drop the subject for a while, but that's okay, too.
I didn't mean to hit you with so much, but I just felt it needed to be said.
It is a great feeling to be nude, and there's alot of people here who are great to talk to, for advice or just to talk.
Be sure and come back to see us.
Oh, and by the way- You don't need to be embarassed about your body. It's exactly the way God designed it to be. Some are bigger, some are smaller, but all are beautiful. Besides, at twelve, you still have alot of growing to do, yet. Be patient.
God Bless
Kevin
