More About Formicophilia
An individual who experiences formicophilia is aroused by having small insects, such as ants, crawl over their genitals. Formicophilia can also describe the pleasure derived from causing someone else psychological distress by having insects crawl over them.
Formicophilia is not limited to the genitals. Some people experience sexual pleasure from having the insects interact with non-erogenous parts of their bodies. Sometimes people who experiment with formicophilia will have the insects enter different orifices until sexual climax is reached.
