I mentioned on an thread I started a few days ago on escort numbers that taking the number of girls on AW within Never very sure how they manage to get here in such numbers and stay.
If worse comes to worse, I hear there are plenty of boats available in Calais...
I think you also have to factor in Seeking and similar sites (even Tinder). They can be hard work but you can get your own SB for much less than punting. They are less likely to be seeing other guys.
There's a theory occasionally put forward by some hardy individuals that escorts, p4p, those seeking handouts where sex is a mere trifling side effect, are not prostitutes at all but actually
in-duh-viduals or ... wait for it ...
real people!
I find this theory a bit dubious and hard to believe personally. It is not, as far as I know, supported by any double-blind, statistically significant, peer-reviewed study and thus one must say that there is no scientific evidence to say that prostitutes are also people.
