Please tell me answers of three questions.

I have three questions. Please tell me the answers.
1. I have expanded my asshole, but it is up to 5.5cm. Assholes of porno actresses are expanded much wider. How do they expand their assholes and prepare it before anal sex?
2. I have wanted to do scat play, but I don't know how to do it. Kaitlyn katsaros is a famous scat performer. I want to be like her. How do she and others do scat play and prepare it?
3. I often drink my piss, but my piss is not so much tasty. I want to drink much more. How should I do to make my piss more tasty?
