It is important to note that identifying as pansexual does not mean feeling attracted to everyone, just as a heterosexual male does not feel an attraction to every female, and vice versa.
And in the context of sexuality, it means pansexuals are capable of forming sexual and romantic attraction to all people, whether or not these people identify within the gender binary.
In a society that assumes heterosexuality unless proven otherwise, coming out can feel like a hugeeee deal! Many sexuality researchers classify both omnisexual and pansexual as terms that fall under the more commonly known bisexual, with the latter acting as an umbrella word but the former giving people the ability to better explain the nuance of their identity.
