Masturbation
It is held in many mental health circles that masturbation can relieve depression, stress and lead to a higher sense of self-worth. Some people who don't have other sexual activity find they get sad or irritable (easy to get angry) if they go for several days without masturbating. Masturbation can also be particularly useful in relationships where one partner wants more sex than the other — in which case masturbation provides a balancing effect and thus a more harmonious relationship.
