A skin-sensitizing formulation is provided in an edible, softgel pill. A person engaged in a sexual activity bites down on the pill, thereby effectuating the oral release of the skin-sensitizing formulation. This allows the skin-sensitizing formulation to be spread to a sexual partner, on any part of the skin or sexual region of the body preferably through oral contact with the partner. The skin-sensitizing substance is spread to the partner directly on the skin or through oral contact or beneath a condom worn by the partner. The skin-sensitizing formulation may include an essential mint oil, analog or derivative, and may further includes an enhancer, rubefacient, counterirritant, anesthetic, K-Opoid Receptor activator, or TRPMS activator. Various inactive ingredients are also disclosed.
