Wikipedia
Haphephobia (also known as aphephobia, haphophobia, hapnophobia, haptephobia, haptophobia, thixophobia) is a rare specific phobia that involves the fear of touching or of being touched. It is an acute exaggeration of the normal tendencies to protect one's personal space, expressed as a fear of contamination or invasion, and extending even to people whom its sufferers know well.
Some people are born with haphephobia, while others may develop it, predominantly after a bad experience. More rarely, it is caused by an extreme reaction to their environment. Sometimes, the fear is restricted specifically, or predominantly, to being touched by people of the opposite or same sex. This is often associated with a fear of sexual assault. Michel Dorais reports that many boys who have been the victims of sexual abuse have a fear of being touched, quoting one victim who describes being touched as something that "burns like fire", causing him to freeze up or lash out.
