Enema

An enema is the procedure of introducing liquids into the rectum and colon via the anus. The increasing volume of the liquid causes rapid expansion of the lower intestinal tract, often resulting in very uncomfortable bloating, cramping, powerful peristalsis, a feeling of extreme urgency and...

s. The term klismaphilia was coined in 1973 by Dr. Joanne Denko to describe the activities of some of her patients, and who did early investigations into the practice.

Klismaphiliacs can gain satisfaction through fantasizing about getting an enema, by actually receiving one, or can also become erotically aroused through the process of eliminating steps to receiving one. Klismaphilia is practiced by both men and women, although as with most paraphilias men are more likely to be klismaphiliacs. Often klismaphiliacs report discovering these desires after a chance administration of an enema sometime in their childhood, but some do report discovering these feelings later on. Klismaphilia is practiced both heterosexually and homosexually. The paraphilia may be used as a substitute or as an auxiliary by its practitioners for genital intercourse. Usually klismaphiliacs carry out a normal life, and successfully engage in this behavior secretly. Klismaphiliacs may also try to get others to administer an enema under the pretense of being constipated. If this is the case they will probably try to conceal the pleasure they receive from this administration.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) classifies klismaphilia under the diagnosis of "Paraphilias, Not Otherwise Specified." The diagnostic code is 302.9. There is usually no question of treating klismaphilics since there is almost never any desire to be "cured". Health treatment for klismaphilia thus is typically only focused on ensuring the techniques employed and chemicals used are not harmful to the practitioner. Caution should always be maintained on the part of the practitioners experimenting with new techniques and concoctions; in certain cases cramps produced by the chemicals used have led to hospitalizations, in other circumstances the effects can even be life-threatening.
