The process known as a sexchance is when a personals sexual characteristics are swapped out for that of the opposite gender
i have never heard of that before, where does this happen mainly? or where did it start
I don't know when it was first done by humans, but it can naturally occur in some specials of animals
oh that is cool, what else can you tell me about this 
in many coral reef fishes the natural sexchange process is a common occurrence.
