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.

Christian Grey is said to have haphephobia, bred of his desperately ambiguous infantile years. Christian experiences panic, pain and feelings of unworthiness when touched. It is one of the issues he is working through with his psychiatrist, Dr. Flynn.
