Well, there are people with no sex whatsoever. With all that could happen... it seems to me to be more of a blender than a spectrum (Hermaphodites would be kind of iffy on a spectrum, as would Trans). It all depends on perspective I guess Mutation = many chances for anything to occur, really
Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
