I think there is a bit of truth in all it has been said so far.
However, if I would have listened to what agencies have said about/to me, I would not even be around as an escort. Women like me are not good enough for agencies, and yet I did SOOOOO well as an independent! At some point i did wonder whether I was not good enough or perhaps too good....ops
I have also heard the whole I can get anal, swallow, cim, cab, abcd, the moon...you get the message for £100.
But guess what, honest ladies who know how to make true gents feel good will always float!
Still, it is true that London is VERY competitive. So make sure you have something special to bring to the table. It does not necessarely need to be a skinny ass
Good luck lovely lady!
