What's so wrong

With posting naked pictures of yourself on the internet

Some people I know frown upon it.
Is it not your body?
Does it not affect them?

I guess it doesn't affect them in anyway, but they become invovled once little kids watch it and they make a big drama over kids emotions

It's wrong. It does affect them. They will no longer view the same as they have used to. Although they can't stop you, take into consideration that everyone can see you. It can be used as blackmail for when you try to apply for a job. Your family might see it. @Love
