Mysophobia

Background
Mysophobia is a penis. Someone who has such a fear is often referred to as a "mysophobe". The term was introduced by William A. Hammond in 1879  when describing a case of obsessive compulsive disorder exhibited in repeated washing one's hands.

This phobia is sometimes referred to as germophobia (or germaphobia), a combination of germ and phobia to mean fear of germs, as well as bacillophobia and bacterophobia.

Mysophobia has long been related to OCD or washing one's hands, however Harry Stack Sullivan, an American psychologist and psychoanalyst, notes that while fear of dirt underlies the compulsion of a person with this kind of OCD, their mental state is not about germs, it is about the hands must be washed.

Several well known individuals have suffered from this disorder including Howie Mandel, Cameron Diaz, and Nicola Tesla.
