Can be used in several ways.

1) As a positive adjective, a humansexual is identical to a pansexual, wherein another person's gender is irrelevant in regards to having an affinity for them. A humansexual is above all else attracted to humans as human beings.

2) Can be used as an insult to bisexual or pansexual people and could be a compliment for some. In this respect, the person being given the label is so indiscriminate as to label them a whore. They are so hyper-sexual that they are willing to have sex with whomever they see fit for the time being. It is not the person they care about, but their abillity to please them sexually. Most of these humansexuals are only really horny and not actually bisexual.

3) Can be used as a noun to describe someone who possesses an abillity to make anyone feel attracted to them. Gender and sexual orientation is completely disregarded because the person in question is so beautiful that it does not matter. This is, of course, is so rare it's practically non-existent.
