Hopefully some of you out there with more experience can lend some advice.  I'm a natural voyeur and so part of the experience is very visual for me.  For example, I would love to have a provider start out with a tease, like upskirt, down blouse, a strip, and then to the main attraction.  Kinda like role playing/teasing.

The thing is, I always find it difficult to ask.  For one if they aren't willing, it puts a bad spin on the session.  Plus, sometimes providers freak before hearing what the request is.  One time I tried asking over the phone whether a provider would be willing to entertain my fetish and she freaked and hung up on me.  I called back to say forget the request; I just wanted to see her, she just said no and don't call ever call back again.  I could understand to some extent because there are some hardcore fetishes and so most providers don't want to hear about them.  

If anyone who has found a good way of asking, it would be very educational.
