If you have not yet seen an escort, the best way to avoid our uncle Leo is to only visit a provider with at least half a dozen review written by guys with a lot of reviews as well.  Anyone will tell you, as a newbie, it is not a good idea to see someone with no reviews for your first venture.  If you do decide to see her, be prepared to offer up some personal info so she can screen you.  If she does not ask for that, RUN AWAY from her very fast.  While it is true that many providers don't want reviews for varying reasons, you don't have the experience to tell whether or not she really is on the up-and-up.

Your age will be a problem for many providers until you have some kind of references.  You can also join a verifi-cation site like DateCheck or Preferred411, to help providers with screening you.  There is a good chance she won't see you because of that.  So be prepared to be turned down.  You need to establish a board presence and you can do that by posting on threads in the Florida forum.  This way, providers can see what you are like.  You might also look around for some providers that advertise 'newbie friendly'.

Where her ad is posted is also a concern.  If it is on a legitimate site like this one, or EROS, or any other national forum, you should be ok.  However, if it was on backpage or a similar site, be very cautious.

By the way, you should invest some $ and get VIP membership here if you don't already have it.  One last thing you might do, contact some people from Orlando and see if anyone can vouch for the lady you are interested in.

Hope this helps.

Thank you, the ad was posted on cityvibe. Regarding the membership I did invest in a VIP membership so thats taken care of. Will look into the Florida boards. Thanks for the help.

you don't see well-reviewed ladies, don't come back bitching about a B & S, C & D, or ROB experience.

There are just to many scams & things that can go wrong.  I'm not saying 'never'...  circle back after you have more experience.  This is a hobby...  not a long term relationship.  
Best Wishes,

I agree with what was said above - newbies shouldn't be TOFTT and seeing unreviewed ladies. There are far too many options for you to take the risk right now. None of your instincts are honed and you could potentially have a very unfortunate first experience. Don't go there.

Swim's answer about age seemed to have combined it with verification. You should expect a little trouble due to your age (I'm in the same category) but not too much. A few years back when I first started reading this board things were quite different. Now, I don't see that many providers that specifically exclude us young guys. Maybe it's the economy, maybe some mature individuals finally popped up. Just make sure that you act mature and not like a generic guy in his twenties and you should be fine with most ladies. As always, make sure to read websites, ads, etc. to make sure they don't exclude you as a rule. Safety first but following protocol is a close second.

I'm a young hobbyist too and it has been one of my concerns.  I have seen over a dozen providers, half of them have been postings on ad sites (backpage, craigslist, etc.) - My experiences with agency providers has been second to none.  Really ur best bet is to go with Agencies.  If you want an independent provider, best if you see someone with 3+ reviews because experiences vary.  As far as EROS sites go, there have been several providers from those sites that promise a lot but don't fulfill expectations.  To sum it up, look for:
1.  Reviewed providers (Best guarantee)
2.  Reputable Agencies.
Just out of curiousity, do you like providders who are your age & younger or ar you the cougar type?
