I think if someone were to go through all the posts here, they could come up with a pretty definitive guide. I could do that I suppose, but I'm too lazy!
Instead, I'll try to apply some personal philosophy that's helped me a lot.
1. Take everything with a healthy double handful of salt. You're an adult (or should be), make your own choices and live with the results and learn from them.
2. Don't sweat the small stuff. Life is hard enough as it is. You don't want to create a source of stress in something that's supposed to help relieve it.
3. Know what you want and don't be afraid to ask for it. The women in this industry have seen and heard it all. Don't be shy.
4. Jesus Christ said it best: Treat others the way you want to be treated. Ok, maybe not in those words but you get the idea.
5. Be clean and hygienic. The ladies are human too and I don't know about you but I certainly don't want to rim someone who smells like shit! Ok, not really philosophical so how about: Cleanliness is next to Godliness?
