The correct answer is "shemales."
Why? Because men who are into shemales are basically sexually confused and fucked up in the head. It's not just something they like - the chicks with dicks strike right to the core of their confused sexuality. It's basically an obsession for them - they love those dicks, but at the same time they feel so guilty and conflicted. "No, I'm not gay," they tell themselves over and over, all the while creeping closer and closer to taking a dick in the ass and swallowing filthy transsexual sperm. So, unlike in other niches where the surfer might just "like" something but not be willing to pay for it, the shemales surfer is obsessed by that feminine shemale with the big dong and it's highly likely that he's willing to get out the credit card to see more.
Trannies FTW
