Hijras, Berdaches, Fa'afafine and more...

Did you ever wonder what "third sex" means?
The social roles and social positions of the third sex vary across cultures.
Lets take a look at a few examples:
+ Hijras (India) - those are often males who take female names, wear women's clothing
- they are much more sexually overt in their behavior than Indian women
- they are considered to incorporate the divine powers of the goddess; they sing and dance at weddings and birth celebrations, and were traditionally they were asked to bless new born babies
+ Kathoyes (Thailand)- also knows as ''lady-boys''
- also wear women's clothing, and violate the norms of femininity in Thai culture
+ Fa'afafine (South Pacific)- typically biological males who take up women's wear and characteristics such as caretaking and teaching
- also take upon some male characteristics like dirty dancing, baseball play, tell bawdy jokes
- they are highly valued as dancers and entertainers who are also typically respected
Berdaches (North American Indian Cultures)- also knows as "two-spirits"
- the characteristics allowed for those vary across Native societies; however,
- they are biological males who wear women's clothing and take up some feminine roles and tasks
- they can also adopt men's customs and clothing
- are often seen as creative and artistic
Pledged Virgins (Balkans)- is a woman who takes up man's role because there is no man available
- no longer thought of as a woman
- she wears men's clothes, does heavy work, and serves as a man in the military

unfortunately today, because of the wide spread of globalization, the "third sex" is associated with prostitution.

So,
HOW MANY SEXES ARE THERE???
