Sensory deprivation
Sensory deprivation is a practice where one or more senses (such as sight, hearing, or touch) are temporarily reduced or eliminated, often through the use of blindfolds, earplugs, or restraints, to heighten other sensations and create a more intense sexual or intimate experience. This practice can range from simple acts like blindfolding to more complex scenarios involving specialized equipment, and it's commonly used in BDSM and intimate relationships to enhance pleasure and trust between partners.
