Salafi,
Just tell me how keeping long hair makes people dirty. I think cutting hair or keeping them is a fashion, men in victorian ages in Europe kept long hair (in braid and in curls). On Indian sub-continent everybody wore turbans - at one point Mughals forbade Hindus from riding on a horse and wearing a turban.
You have raised many interesting questions..it is not natural to have sex in open that is why human spieces doesn't practice it nor in the groups as described by you because human child has a long childhood and lot of attention from two parents and extended family. Human skin needs some protection it doesn't hold very well without clothes. Read Naked Ape by 'Dr Morris' you will find out what is natural and what is not and why it is not.
Mudayaa,
The turban was dress code design to stand out so that everybody knew that this person was a Sikh. This was done to raise an army of people who were brave and stood out and couldn't change their mind as to who they were when moghal armies or sympathizer came to fight them. Turban has nothing to do with Karma but lot to do with fighting off injustice and forced conversion.
