Pansexual IS NOT polysexual or bisexual. Those are completely separate sexualties and shall not be called the same because although they may be similar, they are not the same.
Pansexual is the attraction to someone regardless of what's below the belt (sex and gender). They will not date ANYONE, a common misconception in the community. They just do not mind what the person identifies as.
As I repeat, they do not just date ANYONE. They do not find every person they see instantly attractive. They just do not mind whatever gender their crush/infatuation identies as, or what sexual organ/organs they possess.
Isn't bisexuality the same thing as pansexuality?
No, bisexuality and pansexuality are two completely different terms.
Basically, being attracted to not just two sexes like bisexual implies. They're attracted to ALL genders. This means the pansexual person is attracted to, or can be attracted to, males, females, intersexes, pangenders, androgynes, agenders, genderqueers, bigenders and many more.
1: Are you bisexual?
2: No, I'm pansexual. I like all genders, not just two like "bi"sexual implies. Because pan means all.
A pansexual is someone who isn't influenced by the binaries and labels surrounding gender and sexuality. This can mean attraction to anyone regardless of their gender identity or sexual orientation. Some pansexuals take it a step further to be openly against those labels and definitions, considering them to be destructive and alienating.
During their date he was relieved to find out she was pansexual, and that sharing his transgendered status wouldn't be the hassle it often was with other people.
