I will start from the beginning.
I have always been attracted to the idea of paid sex with a stranger that I just met for the first time, but have never lived out the experience. The appeal is tied the thought of having an encounter where there are truly no strings attached and the whole reason for being in the same room is to simply have sex. There is also an "I'm in charge of this." edge to the fantasy that is not something that ever happens in a normal sexual exchange.
I recently had a small financial windfall and decided that it was time to live this fantasy for real. Just the act of making the decision to do it was enthralling. The next step was to "shop" for the woman I would hire, and the task was akin to being a kid in a toy store with a wad of money. I know that doesn't really paint me in a positive light, but it's what it is. Just the act of looking was a fun and extremely satisfying activity.
