Sorry for knocking off dust of this thread, but it really hits home for me in most aspects OP brought up. Then I started reading the comments, then debated if I should just keep quiet or add my 2 cents....so here I am.
I used this site before the shutdown (didn't realize it was back until recently). Hobbying for about 10 years, Asian male now 40yr old. So AMPs have always been something I stayed away from bc the fear of getting a supposedly 20 something yr old girl and her being older than me. I know it's hard to judge age (especially Asian females if you are not Asian) so I take most reviews lightly when it comes to age.
A few times I checked out a few super raved reviews of AMP girls in their 20's and decided to give them a try. Like Fred stated, they are usually in their lower to mid 30's. Yes, still great looking women with great skills, but not the 20 something "college" chick you wanted to bang. Usually the beginning of the encounter begins with "Why are you here?" questions because it's obvious that I'm around or, at times, young than the provider. Almost always we still have a good session, but there's the awkwardness that lingers.
On that note, that's why it's important to not claim 100% you know a girl's age unless you, in fact, know that 99% of the community would agree with your assessment. Since the forum is much more bare than before, I started looking through this section. Of course the first few ads that I see is Blue and start reading. Lots of claims that a few girls there are in their 20's. Some guys are hard set on their claims and get VERY defensive if you disagree. Funny is that the people who disagree typically agree that the girl is hot and fun to be with, just not in her 20's.
Some of these reviews really want to make me go check out Foxy, but I'm trying to adjust my expectations before leaping in and having one of those "oh well" moments. So to answer some people "Why does it matter?" Because some of us ride that fine line of it mattering.
I'm gonna stay out of the conversation on the economics of these girls, but you are partially correct. These girls are rotated through markets depending on S&D and if they have any kind of drama. Younger girls tend to be the upscale "Indy" providers.
