Bisexuality is a sexual orientation that lets a person get engaged with both males and females in every possible way. Be it emotional, physical, mental, sexual, whatever it is, a bisexual is meant to possess attractions towards both the gender binary identities! Which clearly says, that bisexuals can have two varieties (genders) of people in their personal life. That's how the orientation work and the tribes got segregated depending on the leaning personalities towards homosexuality and heterosexuality. But this particular tribe is completely diverse and you must be prepared to witness the confusion!
Yes, people generally judge bisexuals as confused souls when it comes to deciding between a man and a woman. Ultimately, every bisexual comes to one point as they may select any one of the genders or both (as in polyamorous relationships). But the scenario with Varied bisexuals is very unusual. They select both the genders, and they don't like to be in a polyamorous relationship too. You must be wondering, how that can be possible. With Varied bisexuals, it is wholly possible to have a physical relationship with one gender and emotional relationship with another gender.
