I didn´t know sexual discoveries could still amaze me. It seems that a research at a very highly prestigious university found out most people are unware of their gender. It is a form of hermaphrodite that can go on unnoticed for a long time for the person and the people around them.
Although someone that suffers from this condition develop all the characteristics of the predominant gender, others still happen. It is the case of tiny genitals with the size of half a millimeter and they are not located where one would presume but they were found already in arms, feet and even under a tongue.
Watch out and keep looking for them.
