Read the sections below the heading Provider Relations 101. Then read the posts on the first few pages. Ask specific questions once you've finished reading.

Search for a provider using the ad board for your area. See that she has several reviews by reviewers with several reviews. Be prepared to go through her screening process. Go ahead and pay for the VIP. One month is $30. You can do a lot of research in 30 days.

I just had my 2nd tryst last Friday. 1st one was poor but that was my fault as I didn`t do my home work. This one was a ten because I did my homework. Look at all the reviews of providers in your area or where you will be. Only study the girls that are rated 8/9 maybe a 7 here or there. Next filter by ethnicity, body style, what she does/doesn`t do etc. etc. Basically all the things that you want. If she`s still in the running  go to the top of her profile page and go to her website and see her pictures. If you like them and find her do-able then scroll down and read all of her reviews. If you still want to continue then go to her website and follow her instructions to a T
If no website, then email her. If she responds then follow her lead. She knows what she`s doing.
1st time jitters can be a bitch. Just be yourself, you don`t have to be a male porn star. If your middle aged take a V-pill, they work! If it all works the 2nd time will be even better. Then reach out to other girls then you`ll really get good at it.
I just did all the things that I`ve told you to do and my encounter Fri was a little intimidating at 1st bu then it got real good!! She invited me back and I`m going shortly. It`ll get even better each time. One session was all it took to get  
my sea legs back and I am a happy camper!
Good luck, read my review of her, it`s the only one I`ve written.
