Enema fetishism is a sexual fetish for enemas and is a type of klismaphilia, the general enjoyment of enemas, and hence those enjoying enemas are referred to as klismaphiliacs. This fetish includes not only giving and receiving enemas but also sexual attraction to the equipment, processes, environments, situations, or scenarios. Some may be sexually aroused by the preparations, such as by the feel and smell of a latex rubber or plastic syringe, by the smell of soapsuds enema solution, or by preparing the recipient. Roleplaying (can) often accompanies these activities.
Sadomasochistic activities may incorporate enemas for erotic humiliation or for physical discomfort.
