The present invention discloses compositions, methods, and systems of treating female sexual dysfunction by stimulating the contraction of the smooth muscle of the nipple. The smooth muscle in the nipple expresses trace amine associated receptors and thus can be contracted through a class of trace amine associated receptor agonists such as octopamine or tyramine, but any agent that promotes contraction of smooth muscle can be considered for the methods and compositions described herein. The contraction of the smooth muscle erects the nipple and increases female sexual arousal. The smooth muscle stimulatory compound can be formulated in a solution, foam, ointment, gel, spray, lotion, powder, topical cream, emulsion, slow release capsule or any similar method, compound, or delivery vehicle including a pre-wetted gauze or cotton pad. Additionally, the disclosed composition can be used to improve the quality of a sexual experience, e.g., it can increase orgasm intensity or a subject's interest in sex, of females that do not suffer from sexual dysfunction.
