Red witchcraft means sexual witchcraft, i.e. using sexual energy to obtain the intended result. That means consuming men’s vitality and leaving them dry physically and mentally as well. Depression ensues shortly. An open relationship in this context means that the practitioner needs more “resources” because she drains them too quickly. Men need to learn the functional difference between sexuality (instinctual) and eroticism (amative), practice sexual continence, and just plainly stay away from such women. They are basically parasitic succubi.
