I was actually thinking about this as a 7th & 8th option however I didn't put it in due to the feeling that a lot of people would consider it the "funny option" because people here are silly. It turns out they used Homosexual Female as that instead, but yay for whoever "devoted" those people from the poll.
I think asexuality is definitely out there, though it didn't fit in with the reason I made the poll. I do wonder though, if females are more likely to be bisexual and males are more likely to be homosexual, which gender is more likely to be asexual? Maybe it's even.
