The denial of one's own bisexuality (in favor of speciously identifying as "homosexual" or as one of several synonyms for "bisexual," or eschewing a sexuality label entirely) in an attempt to avoid being the object of biphobia. Refers to actress Cynthia Nixon.
He issued a Nixon Denial in the same breath as he confirmed his romantic relationships with people of at least three genders. But if he wants to identify as "flexisexual," I suppose that's his prerogative.
