shaving is completely un-natural. if (whoever, whatever) meant to create us like bald 10 year old's, it/he/she/force would have created it that way. or, to be more sensible, evolution has put it there for a purpose. multiple purposes, actually.
God need not be involved in a scholarly debate, and evolution actually shows a dramatic decrease in body hair.[/I]
1. warmth - Some believe that pubic hair is for warmth. In prehistoric times, when only a loincloth was worn to cover the penis or vulva, this might have held true. However, if the primary job of pubic hair was to keep the genitals warm, males would probably have hair on the shaft of their penis and more hair on the scrotum to insulate the testicles. Additionally, females would have hair on the skin of their lower torso to insulate the internal reproductive organs. (*um....I know quite a few [unfortunate] males who have hair on their shafts and many females have hair on the skin of their lower torso or lower abdomen, I've seen some serious bushes in my day...)
Prehistoric, now that we've evolved we wear clothes and don't need pubic hair.
2. pheremones - Believe it or not, humans have the same number of hair follicles as apes, except our body hair is generally very fine or barely visible in comparison. Yet pubic and underarm hair tends to be more visible and coarse. It is believed that the tufts of hair around the genitals, as well as under the arms, release pheromones, which act as erotic aids.
Pheromones get trapped in the pubic hair when apocrine glands release an odorless secretion on the surface of the skin that combines with bacteria decomposed by the secretions of the sebaceous glands. The resulting scent is different for individuals due to a genetic complex called the Major Histocompatability Complex (MHC). Studies suggest that women are attracted to men with very different MHCs than their own, perhaps because genetically diverse offspring may be more able to fight off disease. For some people, scents from these areas are noticeable and consciously increase sexual arousal. For others, pheromones might not be obvious but may be detected subconsciously. For example, if you have a mate who's sweat you find very offensive smelling, it is a potential warning to not mate with this person because your genes aren't compatible and could have a negative outcome on your offspring.
These come from the pores, not the hairs themselves.
3. cleanliness - it is said that pubic hair aids in keeping the area clean and free of dust, dirt and debris. One may then ask why men don't have pubic hair on the end of their penis - well, penises come with a sheath on them, aka foreskin, which is now deemed "natural" to remove...
Again, we shower and wear underclothes. We have evolved.
4. infection/disease - Pubic hair provides cushion against friction that can cause skin abrasion and injury. Removal naturally irritates and inflames the hair follicles left behind, leaving microscopic open wounds. The risk also extends to sexually transmitted diseases.
Some clinicians are finding that freshly shaved pubic areas and genitals are also more vulnerable to herpes infections due to the microscopic wounds being exposed to virus carried by mouth or genitals. It follows that there may be vulnerability to spread of other STD's as well.
