Ok ladies, what’s the most important attribute of your best clients (in other words – what makes some guys more likely to get your highest level of service and others to receive less)?  

Is it confidence, cleanliness, physical appearance, size of equipment, sexual experience/ technique, overall attitude, the regularity in which they see you, session length (1, 2, 4 hours), tips received, or perhaps something else?  I know different providers may see things differently but I am curious to see if there are trends that will appear that could help us guys to become better clients and in return receive the absolute best service.

Guys, please include your comments as well as to why you believe you belong in the best client category and why.  It will be interesting to see the dichotomy of opinions from both sides of the equation.

As for me, I have just returned to the hobby after a few years off.  It seems the YMMV factor has definitely increased during my absence.  Perhaps the community has a few pointers on making the most of each encounter.
