You would be amazed by the number of transvestites you can find in Istanbul. They are more numerous then the escort girls and you can find them at any corner in Taksim area. So if you are located there we would strongly recommend to look twice before you pick a "girl" from the street. Most of them do not come to the hotel for both your and their own security but they will have a place nearby to serve you. Considering that checking the internet is safer than going out nighttime in that area we did some research to help you out if you have interest in the transvestite escorting. Here are some useful links:
