I didn't read it like that at all... It seemed to me that the OP is relatively new and he didn't expect them to click the way they did, but when you then assume that it was because the he was astonished that the cam girl turned out to be a real human being with a personality and likes and dislikes and that's what surprised him then I think you're bringing your own bias into it.
To be honest, I think the people who think that cam girls are brainless sex machines are the least likely to hit it off with a cam girl and become friends, because they probably don't ever have the types of personal conversations that could lead to a friendship. People who think like that can't empathize with women at all.
Edit: When I started doing this, I expected it to be all business, too. I didn't realize that I would become friends with several cam girls.
