What Is Figging?
Wikipedia has the basic definition:
Figging is a sexual practice involving the insertion of a prepared “finger” of ginger root or even pepper into the anus. The burning sensation is said to induce intense pleasure. The technique is used by some practitioners of BDSM.
The practice is sometimes said to have originated in a preparation technique for show horses, where an irritating “fig” would be inserted into their anus to induce them to hold their tail high. Others claim that Victorian corporal punishment methods sometimes involved figging to further humiliate and chastise the culprit, as well as preventing the clenching of the buttocks during caning, birching or flagellation.
