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?
I think most people use them interchangably, I call myself bi due to it being a more well-known term and the flag being prettier
The flag is the biggest reason I tend to use Bi more than Pan.
