Initiation Rites:

Some people feel that to be part of a group they need to be "initiated" so they can feel that they "disserve" to be part of the group.

Injection:

In some " medical " BDSM play, a solute (usually a saline solution) would be injected with a syringe in part of the body of the submissive during a scene. The most popular parts of body injected with saline solution are the breasts (men and women) and the testicle (men).
