UTR aren't hard to find the longer your around and read posts by older members.
Lots of good ones. Some ladies do this just for fun and keep a small client base because they have their regulars who match well with them.
Some will be on p411 and not here.
Some are simply referrals.
I rarely post a review anymore unless someone asks for it. First I don't write to brag about xxx. I would write a review if someone knocked my socks off or was really really bad. Everyone has bad days so again would have to be stealing/pimp/up sell or something like that.
I know a few ladies who have dropped out of the hobby who still have my number and email and occasionally shoot a MSG when a bill or want comes along and need help. Again we have seen each other multiple times to build that relationship and so it's a better experience for both.
Best advice is to find a few who really have that great connection with you and keep that relationship going well. Branch out if you want on occasion if a review or post perks your interest but when you find a good thing it's hard to pass it up.
I've seen many GFE providers, but a few really do make it seem like your an old friend / lover and it's so natural it's hard to beat.
Good luck, be safe, treat the ladies with respect, and have fun!
