What should you do if you like to cross dress and your parents don't understand?

In order to successfully cross dress secretly, you need to ensure that you leave no traces, and ensure that your cross dressing plans are foolproof. For example, before going to cross dresser sites, ensure that your parents don't monitor the internet in your house. Assume that your parents could figure your secret out at any moment, so as to ensure that you aren't discovered. Also, have a large amount of excuses to be ready to be used, in case you are found taking some time in the bathroom, or are found in your parents' room. That's pretty much all that I've done to ensure that I won't be caught, and so far it's worked.
