This is really interesting for me. As someone who is bisexual I am attracted to men and women regardless of their birth assignment. As someone said it’s about more than just physical sex. I questioned for a long time if I was therefore pansexual, but for me personally this means something entirely different. Pan is open to all genders, including non-binary, etc. I couldn’t be with someone who doesn’t identify as a man or a woman, which is why I consider myself bi.
