There's a lot of porn on the internet. No, really.
Some of it we look for, some of it we don't. There's enough porn advertising in side bars and so on that even when you're not looking for it, it's not uncommon to stumble across the odd boobie or whatnot.
So let me ask you this, how long do you think you go on average without seeing a naked woman. Or man, if that's your thing. Intentionally or unintentionally.
Me ? I would guess I rarely go 24 hours without seeing a boob. Ain't life grand.
