I'll take it a bot further.
I dislike the terms hooker and trick. As I dislike the terms daddy and baby.
At the risk of being called a loser or a pussy by Gaga (It's OK, I can take the heat :p ), I really refuse to think of the beautiful, young women I fuck as anything less than people. Labels like hooker tend to de-humanize and commoditize an exchange of intimacy, hedonism, and mutual benefits between two consenting adults (i.e.: People).
The fact that facilitating these exchanges requires cash makes it much more honest to me than the idea of dating or formalized relationships where the guy still primarily wants to get laid and the woman still wants to get laid AND make a living does not reduce anyone to hookers, babies, daddies, or tricks, IMHO.
Maybe I'm an idealist, or as I like to call myself a secular hedonist. Maybe I am, in fact, a pussy. Don't care.
I get to fuck a lot of hot, sexy enthusiastic women. Mission accomplished.
