I've spent plenty of money on this kind of shit, I've had people buy it for me and I've known plenty of other people who spend money on it as well. Not DVD's so much...like its been said over and over...welcome to the internet. But the rest of that shit, yeah I know lots of people who do.
I guess its more the norm for girls than guys. If I knew a guy with a pocket pussy I'd clown on him all day.
