I currently identify as bi but what is the difference
Pretty simple:
Bi: Attracted to more than one gender.
Pan: Gender is not a factor in attraction (aka nominally attracted to all people of all genders).
So as an example, you can be bi but have a preference towards men or women, that would be not be congruent with being pan.
Pan seems to be gender blind, i.e. attracted to people with no regard to gender or attracted to all genders.
Bi has one definition in being attracted to both men and women, both sides of a binary.
Bi also has a less common usage to mean attracted to more than one gender which may or may not include both halves of the binary or the entire spectrum.
So if I like the whole spectrum I’m pan? For fucks sake, what am I gonna do with all the bi stuff I made
Keep it? I think Bi is the big umbrella which contains pan, omni and poly/multi.
