Let me begin this by saying before I was ever a provider, I was a dancer and so this concept is very familiar to me.
There is no such thing as owning a hobbyist or client or customer or whatever you'd like to call the gentleman that indulge in the pleasure of our company. A man will choose to see who he desires to see and that is just the bottom line. I had a girl get very jealous of me and begin to take actions that bled over into my personal life because she truly "believed" that a gentleman I had seen was "her" client therefore he should see no one else.
Ladies we should be here to help each other that is the goal of being a part of a "community". To commune and take care of one another. A lot of gentlemen won't dare see another provider for fear that his favorite girl will get upset at him if he does. This is not the way to conduct yourself. Now I've been in the adult entertainment industry since I turned nineteen(a total of 3.5 years). The way you conduct yourself in that environment is a little similar to how you conduct yourself as a provider. When women ban together and assist each other, they make more money (for example two girl specials).
For those of you who know little about men, they don't take well to being forced into anything. Eventually curiosity gets the best of them and they're going to either be able to see who they want without you pitching a bitch fit or they're going to stop seeing you period. The best thing for you to do is adapt to the concept of the community.
Trying to take "ownership" of a hobbyist is a losing battle in the end.
