Well, those two represent polar energies which must come together for an act of creation to occur: the fertility of the female and the virility of the male. Perhaps this is an indication that you are on the brink of a creative period or enterprise, some kind of partnership, whether with another person or a certain energy. Or perhaps it's an indication that there is a potentially fruitful partnership available to you at the moment which you are not fully engaging, if at all. Or on another level, it may indicate some currently ongoing process in yourself in which two polar tendencies, traits, or energies are coming or trying to come into balance.
