used to describe a person who is attraction to others is not limited by sex or gender categories. The use of the identity category pansexual originated in the 1990’s.
“This word ‘pansexual’ was originally coined by Sigmund Freud within his theories on psychoanalysis in the early-to-mid 1900s, but was instead defined as how sexual energy and desire is the basis for all human interaction in life. However the modern usage of ‘pansexual’ has very little to do with Freud’s definition or his psycho-sexuality theories,” (Jakubowski).
