Just doing some self-discovery and some research. This is a question for EVERYONE to whom polyamory is intuitive, practitioners or philosophers.
I believe that people drift to what feels most natural to them. But I also believe that including in-between poll options would be silly, because those votes would cancel themselves out.
I don't believe that gender is black-and-white, easily defined. But I do believe in keeping things simple. This is the only reason for why there are no options for the transgendered, asexual, etc.
If you don't feel comfortable voting without more details, ask away!
I have a feeling about the direction the answers will take, but the only way to test this theory is with a poll.
