Corset fetishism is when someone finds corsets to be very attractive or arouses them sexually.
A corset is a piece of clothing that is tightened around the waist to create an hourglass shape. It is often made of stiff material and has laces or hooks that are tightened to pull the material in tight around the waist.
People who have a corset fetish may find the shape of a person wearing a corset to be very sexy or erotic. Some people may also enjoy the feeling of tightness or restriction that comes with wearing a corset.
It is important to note that having a fetish or finding something attractive does not necessarily mean that it is harmful or unhealthy. As with any sexual preference, it is important to ensure that all parties involved are consenting adults and that all activities are safe and consensual.
