When you go from
male to
female. But a bit later, you think "oh no! I want to be a guy again" and then you
reverse back to a male. But a bit later, you see an elephant and the world around you and what it has come to, and think "oh well, doesn't hurt to be an elephant". This observation leads to your decision to officially change your gender to an
elephant.
I was born a man, but at the age of 69, i decided to convert to a reversotranstranselephantosexual.
