First time having sex with an escort [MF]

I wasn’t very successful with girls in general and had no more than three hookups in my entire life so far which makes me very inexperienced in terms of my sex life. Most of the time I do watch plenty of porn and have bought a big collection of masturbators to jerk off with. One day the idea came up in my mind to have sex with a nice looking prostitute. I did some research and ended up with an interesting agency which offers high class escort girls. I have been clicking through all photographs of the models where each of them has also written down their services. I got more interested in one certain brunette which tends to have a very nice body and face as well. According to her description, she offers girlfriend sex, which is like having sex with a real girlfriend or whatsoever, as the website states. So after all I have decided to book this girl for an one hour long girlfriend experience.
