Well thats mine filled in online. 
Feel sorry for the people that cant decide what gender they are yet, questions are a bit confusing for them 
There are two genders only. I believe this also applies to the animal world.
Sorry Opti, but you have no clue about this subject have you.
Apart from humans who can be intersexed and then have brains of many levels of gender identity, read this basic info on the matter:
"The need for a third sex cell and therefore a third body type in order to produce offspring (and inspire a third restroom symbol) has never evolved on Earth. Such an arrangement would be inefficient and biologically costly. But nature does have multiple examples of more than two "mating types" within a species; clam shrimp have a male as well as two varieties of hermaphrodite, which either self-fertilize or mate with males but cannot mate with each other.
Not be outdone, the protozoan Tetrahymena thermophila has seven distinct "sexes" that can hook up and swap genes .
The stark male/female split in many organisms has long puzzled biologists. After all, having three mating types wherein individuals can mate with the two types other than its own boosts the odds of scoring a compatible partner from one in two to two in three, or from 50 percent to 67 percent; and the more varieties, the higher the odds. For stationary creatures, where finding a mate is difficult, multiple mating types have the advantage, said Laurence Hurst, a professor of evolutionary genetics at the University of Bath. For example, mushrooms have more than 30,000 mating types, Hurst told Life's Little Mysteries"Life IS diverse and goes well beyond just black and white, male and female. It is a fascinating area of knowledge which I have studied and advise, along with other specialist areas, the police on.
As I have said before, so many old geezers on the OOF are so old fashioned in their thinking and, like their forbears throughout history, well out of line with the true natural facts of life on earth.
The days of only the white men, and only men, being always MEN in respect of stunted emotion and having to be "never poofs" being prepared to go to war and kill each other in millions without question, being masters of the universe, are over!
