Spandex fetishism is when a person is sexually attracted to tight-fitting clothes made out of spandex fabric. People who have a spandex fetish may like to look at spandex clothes and feel them against their body. They may also be aroused by touching spandex or seeing other people wearing spandex clothes. Spandex is a type of fabric that stretches and fits tightly against the body, so people with a spandex fetish may find it very exciting to wear or see it.
