it usually is! For your maiden voyage, it really is a good idea to select a well reviewed escort.
The reasons have been much discussed on this board. Once you've seen  a few escorts, if you want to start toftt be my guest,you're on your own. Take the normal precautions when seeing an escort without ter reviews. Google the ph # check other review boards, even post a 411 on your local board.
Good luck  

Bang into head grasshopper -- No Reviewee, NO FUCKEE !

Many girls on every site have NO reviews. Do NOT see them ever as a newbie. Even seasoned hobbyists (smart ones) know to avoid CL, BP, CV, and other sites if the girls have no reviews.

I was asking that a while back.  But after seeing a few well reviewed gals, it made me realize those ads are bogus for the most part.  there are a few that are legit.  If you look up say some numbers off there a few may pop up as reviewed but if you read the review you find its a bait and switch.

U may need to take one for the team. If you find a diamond in the rough great but you may need to be with some shale too. I have had success on BP and CL with ladies for some less expensive high quality fun and I have had a few 2's.

I found it expends way too much energy to shop one of the ad sites, then check reviews...  Start with TER, either New Reviews or Local Regional Board, go to the lady's bio, click the link to her ads, her web site.  Read her reviews & see if she fits your needs.  

More experienced hobbiests may choose to TOFTT, but it takes a lot of time, energy, and to a certain degree increased risk.  Risk of upsell, underperformance, scam, and especially LE.  

I don't say "Never" but it's way too risky for a Newbie.  Been there, done that, got the T shirt, know better now!
After you get some experience, you can circle back & TOFTT if you wish.
