What if you want to wear diapers and you don't want to tell your parents?

People's bladders develop at different rates. You may have one person whose bladder is fully adjusted by the age of 4 and another who may not adjust until 11 or 12. This is nothing to feel self concious about. It is just mearly a fact. There are several techniques that could help you. One is called lifting...if you have a clock in your room you could set it for say 3 hours after bedtime. When it wakes you, go to the restroom. You would have to play with the time to suit you.

Your parents probably don't think less of you. They probably tease you just for fun and they don't realize that it hurts you. The next time they do it just be honest and tell them it hurts your feelings. I'm sure they'll stop!

I'm gonna assume this is for "Pleasure" =P Have a serious discussion with your parents. Get their attention. Tell them it's not something you can control, and that you'll be responsible about it, you could do a lot worse thiings then wear diapers =)
