Very true Naomi,
Plastic Surgery, hormone treatment and fewer clients than regular Escorts are the main reasons.
Normally they charge 50-100 euro more than regular girls because they have a smaller market to cater towards. Also all the hormone treatment means they can only work on certain months when their bodies are able. Plus the same reason goes for plastic surgery too. These babes have more recovery time to consider before planning a tour. Remember most have cocks and some have pussy's installed.
TV-Girls are different. They only have to worry about the small market available to them. At the same time TS and TV girls do have a lot of time-wasters coming to see them. Guys that are interested in "experimenting". But some of these guys just run when they see the cock dangling in front of them.
These girls have a lot of shit to deal with. I really respect them. They have a tougher job than the regular girls.
God bless them.
