A training collar is a collar worn by a submissive partner in a BDSM partnership to signify a more serious relationship level. It can be compared to an engagement or purity ring in a vanilla partnership.
More About Training Collar
A training collar is given to a submissive to symbolize a step forward in the relationship between the dominant and the submissive. This is the stage in the relationship where values and expectations are more deeply discussed. If during the training collar stage the dominant determines that the submissive is the right fit, a final collaring ceremony may occur which is often similar to a wedding ceremony.
In some cases, a submissive wears a training collar while being mentored by a dominant. The submissive is trained and mentored by the dominant before being released into another dominant’s possession. This is considered a grooming process for submissives.
