Women around the world are carrying out a practice which not only leaves them in pain but at increased risk of HIV. These factors in turn increase the chance of the women contracting sexually transmitted diseases including HIV. Women in developing countries are putting their health at risk by carrying out a practice known as 'dry sex'. This involves drying out the vagina using substances from sand to pulverized rock to bleach, in order to make sex more pleasurable for men. Dry sex is known to be carried out in South and Central Africa, and Indonesia.
