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.
