Clothes made out of them enhance your awareness of your sensual self and restraints made out of them can cling like a second skin. The mind is the biggest erogenous zone and role playing and mock acting can be very hot. As for corsets and high heels, they are both restrictive garments that enhance the curves of the body, and that work really well as part of erotic power play. They are some of the classic fetish items. Another fetish many people have is smooth skin, with no body hair.
Shaven skin is silky soft, completely and utterly naked, and very vulnerable.
Shaven legs, armpits, or genitals can feel very different indeed than hairy ones. Feeling a need to experiment with and explore your sexual emotions is neither sick nor illegal. The majority of scientific books, written about erotic power exchange, have been written by psychologists and psychiatric therapists. And quite a lot of them are hopelesly outdated. DSM-IV is recognition by the therapeutic community that SM can be practiced in a psychologically healthy way.
