Chemical play refers to the use of chemical substances, often in liquid form, during sex. These chemicals are means of increasing excitement through different tactile sensations. They are applied sensually through caresses and sometimes, even using sexual body parts such as the penis or nipples. Substances used include chili peppers, tabasco, lemon, cinnamon, Bengay, Tiger Balm, and Vicks Vapor Rub. These are applied anywhere on the body, including favorites such as the genitals, anus, inner thighs, and tongue.
