Here are some fetishes that are more extreme than just what colour hair gets you going!
Squashing Fetish: obsessed about getting squashed by an XL woman

A little known sexual fetish called “squashing.” The deed involves exactly what the name suggests — one partner is body slammed or “squashed” by a much heavier counterpart.

Looners: obsessed about balloon fetish
Balloon fetishists, or Looners, are folks that are sexually stimulated by and/or have sex with balloons. This fetish is indirectly related to latex fetish. Like latex, balloons are tactile and supple and imitate the consistency of human skin. However, unlike plain latex, balloons have the ability to expand, which for some looners, is representative of the swelling of primary and secondary sexual organs during arousal.

Inflation Fetish

When asked if he remembers his ‘first time’, 45-year-old  Ben from Minnesota chuckles: “Oh yeah, it was a complete disaster!” His usually calm tones crackle with excitement as he confesses, “I was overzealous and set my pump pressure too high. I hadn’t paid attention to the expert information online, and I got a bad case of the dry heaves. I was really sick!”

Ben isn’t talking about losing his virginity, he’s recalling the first time he wormed a lubricated tube 6″ up his bum – far enough “to avoid air leaking out” – and bulged his stomach out to a “sexy, round ball shape” using an aquarium pump, then gradually blasted out the gas, ahem, naturally.
