Etiquette for Sugar Daddies and Sugar Babies

For Sugar Daddies:
Treat the ladies with respect, not like prostitutes. For the most part they are just girls next door who are trying to get out of debt. Many have professional and educational aspirations, so feel free to offer the perspective and advice of an older experienced person. I am sure they will appreciate it. Of course, every now and there will be a money grabber. In that case, use them and abuse them, just like they do to you.
And remember, this type of arrangement is not a relationship. You are both there for a mutual exchange of some sort. If you were not exchanging your money or gifts, I am sure these nice ladies would just get up and walk out within seconds (there are some exceptions that I can think of).

For Sugar Babbies:
At first, don't mention anything about money or gifts, or your finances and how much help you need. Seriously, I had one lady tell me over and over again how much she loves money and gifts, within minutes after she first met me. I think it shows lack of class, and makes us want to treat you like dirt. It shows me immediately that as long as I give you money I have the right to treat you like crap. And I know you don't want that, so heed my advice, please.
Keep conversation to things of general interest like work, school, current events, movies you saw, i.e. first date type of subjects. After a while, if the subject of 'gifts' doesn't come up you can raise it like: 'so David, what makes you look for a sugar baby'.
You can ask us, gently, about our personal situation, our marriage, relationships etc. But don't be as crude as to say something like 'so, how often do you cheat on your wife?' I kid you not, I have been asked that. People have no manners anymore!
Enjoy your time with the sugar daddy, and treat it like a little vacation. You never know how long it will last. Maybe you will find a more generous sugar daddy and leave the one you are with now, or maybe he will find a sugar baby that is sexier than you and leave you. So don't take anything for granted.
