The only other one is asexual, I think. Meaning you don't feel the need to act on sexual urges. There are different types, though. Homoromantic (wanting a romantic relationship of the same sex), Heteroromatic (wanting a romantic relationship with someone of the opposite sex), Biromantic (wanting to be in a romantinc relationship with someone from either sex), and Panromantic (wanting to be in a relationship with someone of any gender).
I'm not too sure if transgender counts as a sexuality, though.
