Some of the best sex I have ever had was with escorts. In Australia the sex industry is legal and the girls have websites and there are review forums and so on. I think the men who get the most out of escorts are those who have a bit of experience with casual sex and one night stands.
The professional escorts are there to give you a good time, and it's up to you as client to steer things in the direction you wish it to go. The other thing that may seem odd but is true is that the girls can and do get turned on by clients. Orgasms are easy to fake, but not wincing with post-orgasmic clitoral sensitivity, delaying intercourse for a few minutes, or ejaculating, which happened with girls I was with a couple of times. This aspect of professional sex is possibly the best part, the way it is no-holds barred for the period of time that you and her are together.
My experience in Australia is that you need to pay a minimum, but more money doesn't necessarily mean better service. But if you find a good escort and are confident in yourself, you may well have the best time of your life.
