Of course we are NOT attracted to EVERYone! Personally, I am not attracted to many at all.
I think that the main difference is that a healthy pansexual mentality somewhat diffuses (or maybe, confuses) the polarization of a two-gender (bi- or ambi-)sexuality.
As with other aspects of life, I see a spectrum.
you can also be asexual and pansexual methinks.
I can not conceive of this, unless you mean asexual in regard to OTHER people, but sexual in regard to hawt shoes, warm sun, tight shorts or some other physical thing or sensation, not related to another person.
What do you mean? How can you be pansexual and asexual at the same time?
