Formicophilia

Formicophilia, a form of zoophilia, is the sexual interest in being crawled upon or nibbled by insects, such as ants, or other small creatures.

The desired effect may be a tickling, stinging, or in the case of slugs, slimy sensation, or the infliction of psychological distress on another person.

[3] The term was coined by Ratnin Dewaraja and John Money in 1986 from the Latin formica (ant) + the Greek philia (love).

[2] In the first reported case study, the patient had started keeping ants in a cupboard of his room as a hobby when he was nine.

John Money suggested that the paraphilia developed as an alternative outlet after his normal sexual expression became associated with the trauma of his father's punishment.
