With billions of people existing together on this planet - and now thanks to the internet - those with, ahem... different hobbies can now group together and start to get into all kinds of things.
They are the nappy lovers, furries, and women who fall in love with buildings. Welcome to the world of the weird subculture.
Some of them are very creepy indeed...
There is a community of (mostly) men who have sex with and sometimes marry ultra-realistic silicone women. The dolls start at $6000 and are seen as ideal for those who don't want to deal with human emotions.
A balloon fetish is a sexual fetish that involves, erm... balloons. They are split into two communities: looners who pop balloons, and looners who protect them. Both love shagging balloons, though.
This is characterised by the intense desire to amputate a healthy limb. Remember that time you had the sexy urge to cut off your own feet? Nope, us neither.
These men like to spend their time dressed in elaborate rubber body suits and face masks, complete with breasts and a vagina, designed to make them look like the glamorous women they are not. They are also the stuff of nightmares.
The Diaper Pail Friends are a subculture that gets turned on by wearing nappies all day. They also meet up and discuss what kind of nappies to wear and which absorb the most moisture. Gross.
A nice group of people who love to get their kicks from being suspended from wires buried in their skin. Sexy.
Embrace your inner Rocky Raccoon and join the Furries! They are a growing subculture of fetishists who love having sex in animal costumes.
This is an orientation in which people find objects attractive. They also find buildings sexy. One lady married the Eiffel Tower before running off with the Louvre. Hubba hubba.
No, not the famous Welsh band from the 90s, but a community of men who literally love to feed women until they burst. The (again, overwhelmingly male) feeders take fat fetishism to the extreme - viewing hugely obese, bed-ridden women as the ultimate in beauty. To make sure the woman reach the heaviest weight humanly possible, they feed them gallons of liquid fat through a funnel every day. Sick.
