Definition - What does Hood mean?
A hood is a BDSM gear used to cover the head of a submissive. Its main purpose is to conceal the identity of the sub. This gives them more freedom to let go of inhibitions and enjoy the sex scene. It may also be used to deprive the submissive's senses, making him or her feel more vulnerable. For the scene's dominant party, a hood can help conceal the submissive's person, making it easier to objectify them.
Kinkly explains Hood
A hood can be made of leather, latex, cotton, or spandex. The different materials result in varied levels of sensory deprivation. For a dom, it is important to remain aware of the sub's comfort and tolerance. A safe word should be employed, in case things become unbearable. A hood should fit well. If it's too loose, it may not do what it's supposed to do. If it's too tight, it can get too uncomfortable in no time.
