In brief: Political terms
Defining one's sexual identity is your business, not your doctor's.
A person who feels some romantic attraction to both men and women / males and females may self-designate as "bisexual"; someone often having insertive sex with both is probably practicing this; calling onesself pansexual advertises openmindedness and liking all lifestyles and types of male and female sexual identity.
