Seyz,
Have you tried shaving your pubic region entirely? You may have very active apocrine glands, and hair serves an important role in "disseminating" the smell. Here’s a little info about where genital stink comes from:
Apocrine Glands: The Odor Factor
Apocrine glands are located primarily in the underarm and genital regions. There are approximately 2,000 apocrine glands in the average human body. Like sebaceous glands, apocrine glands secrete their contents to the skin surface through hair follicles.
Apocrine glands secrete a milky sweat that is rich in organic materials. This secretion, when broken down by bacteria on the surface of the skin, is the chief cause of body odor. This sweat is produced in response primarily to hormonal stimulation and secondarily to emotional stimuli such as fear and pain. Apocrine glands are present from birth, but do not mature and secrete until the onset of puberty. Therefore, body odor is not usually a problem for children, and is rarely a problem for the elderly as the secretions of apocrine glands are reduced with age.
