Knotting refers to a sexual practice or fetish that involves the act of tying or binding a person's body using various types of knots. It can involve using ropes, cords, or other materials to create intricate patterns or restraints on the body. Knotting can be a form of bondage or BDSM (Bondage, Discipline, Dominance, Submission, Sadism, and Masochism) play, where the act of being tied up or tying someone else up can be sexually stimulating or pleasurable for some individuals. It is important to note that engaging in any sexual activity or fetish should always be consensual and practiced safely.
