If you've had unprotected sex recently, or even protected, there is a possibilty it could be pubic lice.  Also, I know that personally when I get itchy it's because of dry skin or because of razorburn, hope that helps!

Sounds like the start of a yeast infection.  Contact a doctor if this is your first for medication to treat the cause and the itch.

Q. What causes the skin to itch after dialyzing?\n\nA. Itching is a common complaint of patients with kidney disease. Among those requiring dialysis, 40-90 percent experience this symptom. The cause is unknown, but it is likely due to a combination of factors as indicated by the variability in symptoms and response to therapy. Possible contributing agents include dry skin, high blood levels of vitamin A, calcium, phosphorus, parathyroid hormone, beta2-microglobin and increased histamine levels in the skin. Additionally, other disorders such as the underlying cause of the patient's renal failure, allergies, gallbladder disease and cancers may be the source of itching in persons with kidney disease.\n\n \n\nThe onset, course and response to treatment are variable. While a majority of patients first experience this symptom after the initiation of dialysis, some patients may begin to itch before reaching end-stage renal disease (ESRD). Itching occurs equally often among patients dialyzing by hemodialysis or peritoneal dialysis (PD). The itching may be localized to one area of the body or generalized. The itching may be constant or intermittent. Itching\n\nItching is a common complaint among dialysis patients, although not all patients are troubled by it. While no one knows the exact cause(s), itching may be brought about by:\n# Dry skin\n# High Phosphorus Levels\n# Allergic Reactions\n# High Blood Levels of Parathyroid Hormone (PTH)\n\nAmong dialysis patients, itching is most often caused by dry skin. It occurs because the skin is not making enough oil to moisturize itself. It is important to keep the skin clean and moisturized. It may help to use a moisturizing soap when you bathe, to apply unscented body oil, and to use body lotions.\n\nAnother factor related to itching may be your diet. In your blood, phosphorus combines with calcium to form phosphorus-calcium products. Some of these phosphorus-calcium products are excreted through your skin and this may cause you to itch. The best way to avoid this is to keep your phosphorus level normal. Maintain your dialysis diet and take phosphorus binders with each meal or large snack as directed.\n\nAllergic reactions to the dialyzer, blood tubing or medications may occur during the hemodialysis treatment. Keep a record of how you feel during your treatment. Maintaining such a log may help you to pinpoint the causes of your itching. Discuss how you feel with your doctor or nurse. There are medications available that may help you.\n\nA blood test can tell if you have a high level of parathyroid hormone (PTH). PTH levels are often elevated in dialysis patients due mainly to a decreased calcium level and an increased phosphorus level. This condition stimulates the parathyroid gland to secrete excessive hormones. This can lead to bone disease. Symptoms may or may not occur. If symptoms appear, the bone disease may already be severe. The most common symptoms are bone pain, joint discomfort and itching. Treatment includes controlling calcium and phosphorus levels with phosphate binders and taking Vitamin D. \n\nhttp://www.aakp.org/AAKP/RenalifeArt/2003/itchyskin.htm\nhttp://kidney.niddk.nih.gov/kudiseases/pubs/hemodialysis/\nhttp://www.davita.com/articles/dialysis/index.shtml?id=\nhttp://www.biomedcentral.com/1471-5945/5/7\nhttp://www.rdoctor.com\nhttp://www.kidneypatientnews.org/kpt7.htm\nhttp://www.americanheart.org/presenter.jhtml?identifier=47\nhttp://www.symptomat.com\nhttp://www.mayoclinic.com/health/metabolic%20syndrome/DS005\nhttp://www.nlm.nih.gov/medlineplus/metabolicsyndromex.htm\nhttp://www.medicinenet.com/metabolic_syndrome/article.ht

There is a good product for sale called After Bite, a clear liquid that you apply to the bites.  It comes in a compact tube, easy to keep it handy.  I think it contains mostly ammonia.  It makes the itch go away.  If you've been scratching like crazy and the area is raw, be careful, because this stuff will burn a little bit.

You could have a skin condition called "eczema".That would explain the itching and dryness.That might explain the problem with the sweat too.The scaly skin could be so thick that it's covering your pores/effecting your sweat glands somehow.

It could be a symptom of Hepatitis or something called Lichens Planus (I think I spelled that right). Make and appointment right away to see a Dermatologist so you can be properly diagnosed and hopefully get some medication to get rid of the itch. The longer you wait and the more you scratch, it could leave really bad scars that can take up to 2 years to fade away.

Etiology\n\nThe perianal skin tends to itch. Pruritus ani has many causes: (1) dermatologic disorders (eg, psoriasis, atopic dermatitis); (2) allergic reactions (eg, contact dermatitis caused by local anesthetics, such as "-caine" preparations, various ointments, or aromatic and other chemicals used in soap) and eczema after ingestion of certain foods (especially spices, citrus fruits, vitamin C tablets, coffee, beer, and cola), although it is doubtful that true allergy is a causative agent; (3) superficial infections with fungi (eg, dermatophytosis, candidiasis) and bacteria (secondary infection caused by scratching); (4) parasites (pinworms and, less commonly, scabies or pediculosis); (5) oral antibiotics (especially tetracyclines); (6) disease processes, such as systemic diseases (eg, diabetes mellitus, liver disease), proctologic disorders (eg, skin tags, cryptitis, draining fistulas), and tumors (eg, Bowen's disease, extramammary Paget's disease); (7) hygiene, either poor with residual irritating feces or overmeticulous with excessive use of soap and rubbing; (8) warmth and hyperhidrosis caused by tight body stockings, jockey shorts, warm bed clothing, obesity, or climate; and (9) psychogenic response. Hemorrhoids usually do not cause pruritus ani.

try changing your soap or towel.  I doubt it is the water because then your hand would itch after washing your hand or doing anything in tap water.  IF the itching stops or continues with one gone or the other gone, you know you have you culprit
