this is what i don't understand. these two concepts sound exactly the same to me
to me, pansexual means that gender isn't really a factor for you. If them chemistry is there the person can be transgender, male, female, or genderless and you can still be attracted to them
in all honesty I'm probably more pansexual because idgaf about what people identify as in terms of gender but I still prefer the bisexual label. I like to keep things simple
