Please add a description to your stamp if you can to educate the ignorant people. If you can't come up with one then I can provide a simple one for you to add:
"Pansexuality is being attracted to somebody regardless of gender or sex. Sex meaning what they were born as and gender being what they identify as. Gender can go far beyond male and female after all, spanning into things such as androgynous people, unisex, and gender-fluid. Those are only to name a few of the many gender identities."
i dont feel as if the other person explained it better. there are more than just 2 genders, which include genderfluid, agender, ect bi means you are only attracted to the male and female gender pan means you don't really care for gender at all and you can just identify as anything you want, since pan has no preferences. so basically it's only for personality???? and not your gender. u feel me bro
