As a biromantic asexual woman, I refer to myself as bi or pan interchangeably.
When I looked at the definitions and using my background knowledge, it appears that both sexualities love regardless of gender.
While bisexual people like men and women, I also heard that very few of them won’t date other genders. Some bi people will only date cis men and women, others only men and women in general, and some will date nonbinary people and not care.
So anyway, don’t both sexualities love regardless of gender and find everyone attractive?
Using labels for attraction and gender is a way to bring people closer together and share communities and issues. It’s not limited to dating, though obviously it helps to find people who fit each other’s attraction. “Oh you’re pan? That’s awesome, I’m gay and this is my boyfriend!” / “I heard Stacy is single, let’s hook her up with Jane, tee hee” / “Does anyone know where I can find a gender-neutral restroom at the airport?”
