Apparently pansexual means a liking of everyone. If one is pansexual they are heterosexual, homosexual or bisexual. A pansexual person likes everyone regardless of their the sexuality of another person.
Researching the term pansexual brings up the idea of you say tomato (toma toe) versus tomata (toma ta). The term first came to light and seems to be popularized by celebrity quips. Miley Cyrus recently declared her pansexual preference.
Being pansexual does not require one engages in sexual activity. The implication is that one likes everyone. Sounds like a nonjudgmental approach. More research on the use of the term is suggested before one announces there choice of label. For example, if I am physically attracted to someone who turns out to be a homosexual female does that make me a lesbian.
