Interesting thing about squirting is that its as varied as the shape and size of pussies.
It can vary from a tiny dribble to a fountain. Some women can control it and some can`t.
It can come on its own without orgasm or only with orgasm.
sip...
And you know it can really be just pee? Its commonly done in Porn, either its very clear pee (wich the lady prepare a lot for) or they put some water in there so she can let it go to simulate it.
Porn and escorting are similar and different at the same time. Porn actress mostly do it with young stud or at least fairly attractive men (that is unless they shoot for Pierre Woodman or Ron Jeremy lol) while escorts will see all type of dudes, some they probably find really not attractive. A 20 porn scenes can take hours of shooting, just as an escort will see sometimes 3-4 clients or more in a day and have more sex than she would like to. Difference here being that the escorts do it more "naturally" as they don't have to pose for the camera or such and are not directed.
But in both cases, one thing in common is it is probably very hard for an escort to orgasm in both type of "work" , so let alone squirting.
So sorry to be the party crasher here, but altough it may happen ocasionally the "right way", i am pretty sure most of the times you guys just got peed on ;P
