Cock Torture (CT) in the SM context means causing intense stimulation, discomfort or pain to the penis, usually including the foreskin, if present, using hands and any number of improvised or purpose-made devices. This is not so horrific as it might sound to some men: the penis is often regarded as a particularly delicate and sensitive part of the anatomy but although there are specific health and safety issues to consider the organ is sturdier than you might think, and can take a good deal of punishment without serious risk (think of what it endures during energetic fucking).
