Autumn... I think I might get what you're saying here.
Let me be frank here... not all providers like or love each other. And the few who get along well may not always want to hear about a guy who is one of their regulars seeing someone else. Having said that, it is important to be kind of thick skinned about such things. There are some things you can change in this lifestyle and there are somethings you can not. And a man's desires are fairly fickle.
If I found out a provider put me in a holding pattern on a meeting because she was having fun with a client who was a regular of hers or whose company she enjoys, should I be upset about that? I can be... but it profits me nothing to do so. If she's really that important to me then I'll wait and see her. If she's not... its on to the next one.
Autumn, I respect where you're coming from here. Unfortunately, I doubt much will change from it. Guys are just as bad as women when it comes to gossip. And when it comes to making parallels between to providers who are close or know one another in some way... they're going to do it; quite often in a public forum such as the review board.
My advice, dust your shoulders off and keep your head up. I'm pretty sure there are things your extensive tallents are better served focusing on... Like me
