A person who loves without limits. A person whose romantic and sexual love is not limited to a specific number of gender/sex.
Naomi is a polyamorous pansexual. She loves her anchor, Josh, but she also loves Jonathan and Imani. She is in a happy, loving relationship with all of them.
Being pansexual means you don't have to worry that someone might be of a gender that you aren't attracted to, only worry that you are a gender that they aren't attracted to.
panesexual people don't care if you're male, female, trans, gender queer, genderfluid, nonbinary, etc. they are pretty much just attracted to anyone, no matter what they're gender identity is.
