The name of the game is variety FOR MEN. That being said, I always give references and oddly enough my clients come back eventually. Us providers don't own any gents and vice versa. But I have seen some around 10 years who won't go anywhere else. If they are satisfied with me, who am I to change a thing.

On a personal note in real life, I'm more comfortable with only 1. But as I said, men have a more active sexual imagination than most women. Myself included.
