Pansexual doesn't mean "I'll fuck a tree or a dog if I want." Pansexuality takes into account there being more than just two gender identities. A pansexual person may be into males, females, nonbinary people, transgender people, agender people, genderfluid people, intersex people (intersex being a sex, not a gender identity), etc and so forth.

Bisexuality is where someone is into two genders/sexes. Pansexuality is more than two.
