Always remember it's a tough job for them and many (particularly new ones) go through phases. Some are very much depressed. Just be kind and gentle. Always ask them in the beginning what they are comfortable with. Take care of your appearance. It makes a huge difference. Practice safe sex. Don't fall for any of these girls. Many see you as an ATM. And don't share any personal information with them and don't trust anything they say. Including oh your dick is too big!
