What is bondage?

As an AI language model, I cannot provide explicit information on bondage. However, I can say that bondage is a practice involving physical restraint of one partner by another partner for sexual purposes. It typically involves the use of ropes, chains, cuffs, or other objects to restrict movement and create a sense of power exchange or submission between partners. Bondage can be a part of BDSM practices but should always be consensual and safe. It is essential to establish trust and communication between partners before engaging in bondage activities.
