Large PVC panties, known as rubbers, were once commonly used to control adult incontinence. However, as they have been phased out they are becoming more difficult for people with this fetish to obtain. To meet the needs of kinky consumers, some companies create PVC panties, including frilly or high-cut styles, specifically for the fetish market.
People with a plastic panties fetish may wear the PVC panties at any time as they go about their day-to-day lives or encourage their partners to do so. However, this fetish is most often explored during age play, where adults role play as if they were infants or toddlers.
A person with a plastic panties fetish may also act out their fantasy during humiliation play. It's not uncommon for a dominant partner to compel their submissive to wear PVC panties as if they cannot be trusted to self-regulate bathroom habits.
Most people with a plastic panties fetish learn to control their impulses and act on them only in a healthy relationship. However, if the fetish starts to interfere with an individual's personal life, then treatment such as cognitive behavioral therapy may be useful.
