I have only seen 3 providers but it would be quite difficult for me to forget them in the future.  I keep a folder in my computer with a diary of my encounters, so I remember what I learned from the experience  and what the lady is willing to do with me.  I just happen to include pictures with my archive.  

But if you are talking about the visuals of the experience, I am having a hard time remembering , what I want to remember from a girl I saw yesterday ! I guess we just have to live in the moment.

I try to find something special or unique about each session.
Whether it's something about the provider, the ambiance, or the location.
Helps when remembering a lady.

Sometimes even the phone number helps me remember who the provider is.
One provider's phone number is ingrained in my memory because of how easy it is to remember.

my first

sure do..i reread it the other day i must admit i sounded like a newbie dipshit..which i was..practice does make perfect..i am getting so good at it now i turn myself on reading my own review..

My first escort date..

The review would have read something like this.

General Details

I was shitting my pants.. Got lost in my home town.
WTF is a two call system? I'm confused.

Juicy Details

She tolerated my stupid ass, and actually got me to cum.
My gutless display really seemed to annoy her.
The look of absolute boredom on her face was priceless.
I said all the wrong things, and managed to get lotion all over the in call.
One fuck up after another, and she didn't throw me out!
It was a pathetic display on my part, and I really should thank her for not laughing at me.
That is in my face anyway. Because I know as soon as I left she busted a gut.
Poor girl really earned her money..

It was so bad. I almost quit the hobby before I got started.
Yup. There it is!!

.... I can still remember the name of my first reviewer even though they aren't online anymore

no, they have not been deported - they are here as Democrats.

I remember all of the providers that I've seen over the years, even the ones that I haven't reviewed.  I have reviews that date back to 2000, but they're not on TER.

My first TER review dates back to 2003 and I do have some fond memories of her.  Only a couple of the providers who I've reviewed are still active today, all of the others have retired.

Oh yeah, I remember them all

All the way back to the very first girl who took a chance on me when I had no references nor any idea of what the hell I was doing. She was the one who introduced me to TER and gave me some legitimacy by asking me to write her a review. I had no idea what she was talking about so she showed me this place.

I sometimes go through my reviews of providers who've retired and/or have been delisted (for both good and some very very bad reasons). Even with the worst offenders, my time with them was fun and it was sad watching as they self-destructed. One self-destructed on America's Most Wanted and the shock of remembering her as I saw her and later finding out what she really was changed the way I selected providers for good.
