Amphierotic is an adjective describing people who are bisexual, yet typically feel attraction towards and form relationships with people of the same gender.
Hungarian psychoanalyst Sandor Ferenczi coined the term. However, his meaning was a little different to the way we use the word today. According to Ferenczi, people who are amphierotic have a fluid erotic identity which may be male or female, or both genders at once, at any time.
The term is a combination of the Greek terms amphi, meaning “on both sides,” and erotikus, meaning “sexual or passionate love.”
