For many people the feel, smell and touch of rubber, PVC, Neoprene or Lycra is a huge turn on. The way it clings to the body and the ‘encasing’ sensation it creates can border on bondage.
For many Lycra or Spandex fetishists the thrill also comes from the association with sports and uniforms and having a very thin piece of material covering their ‘private parts’ is part of the turn on. Similarly those into rubber often find the way it clings to genitals and private areas is half of the fun.
Latex or rubber fetishists sometimes refer to themselves as “rubberists”. Gay rubberists tend to call themselves “rubbermen”. Rubber and PVC can be transformative for some people, becoming a costume that lets them be someone else or give release to behave in a different manner.
From Wikipedia –
“Latex fetishism often involves dressing up in the material, or looking at it worn by sexual partners, or fantasies about wearers of skin-tight or other latex garments, such as divers and workers wearing industrial protective clothing.
Some latex enthusiasts are also turned on by the wearing of draped latex garments such as cloaks. Other rubber paraphernalia, such as wet suits, gas masks, splash suits, Mackintoshes, galoshes, Wellington boots, rubber/plastic pants, and diapers are also often added to the scenario. Heavier fetishists often attempt duplicating all kinds of “everyday wear” into a rubber counterpart. Some PVC enthusiasts are turned on by PVC Hazmat suits and other forms of industrial protective clothing.
One reason why spandex and other tight fabrics may be fetishised is that the garment forms a “second skin”, acting as a surrogate for the wearer’s own skin. Wearers of skin-tight nylon and cotton spandex garments can appear naked or coated in a shiny or matte substance like paint. The tightness of the garments may also be seen as sexual bondage. Another reason is that nylon-spandex fabric (preferred by many spandex fetishists) is often produced with a very smooth and silk-like finish, which lends a tactile dimension to the fetish – as well as a visual one.”
