Sometimes I sit backwards on the toilet.  Do you think that's normal?
Why would you sit backwards on the toilet?
Because I just feel more comfortable sitting like that.
A toilet is designed to be sat on facing forwards. Unless you have a toilet that is meant to face that way you should always sit the correct direction on the toilet.
Why? I'm going to sit backwards on the toilet.
Because you could make a huge mess using a toilet like that in a way they're not supposed to be used.  Think about the poor person who might have to clean up after you!
