It's interesting how escorts choose a name. Many just choose some vague moniker like JockXXL or HugeTop, or something impersonal. While others make up a real-life type name like Joe Smith or Paul Jones. Personally, I find that the I'm much more likely to hire an escort with a "real" name as opposed to fake sounding descriptive names. Generally, I've found that the "real" name guys tend to be more "real" escorts, as opposed to all the fakes out there who are regularly denounced on this forum.
There's certainly no hard and fast rule, there are guys on both sides who are "real" and those who are fake. However, if you look at the escorts who are named by posters here as their all-time favorites, I think you'll see most have either a full real name (first and last) or at least a first name.
My best experiences for example have been with Jason Markus, Steve Roberts, Mike Grey, Rafael Alencar, Mario Ortiz, Rafael Carreras, Adam Michaels, ANYCStud, Vito Gallo, Bruce Beckham, and Marek (porn name Jake Havoc). Only one with a descriptive moniker.
Of course many of these are pornstars who more or less have to have a "real" name so they can have a memorable identity.
On the other hand, most of the fakes I've come across have one of those descriptive monikers. I won't name them, but just look at the fakes named on these forums and you'll see what I mean.
The thing is, the monikers are hard to remember and mostly meaningless. Which is the point, I think. I can't remember all the XXXLthis and Jockwhatever names. The straight guy who is trying to make a few bucks without really having sex doesn't intend to be around for long. He doesn't want an identity. He just wants to have a name for a temporary ad that will draw some eyes.
Maybe my perception is flawed, but it looks like to me that the more serious escorts go to the trouble of choosing a "real" identity. It's only a generality, of course, but that's the way it looks to me. So my message to serious escorts is: choose a real name and stick with it if you haven't already. It says something about you.
