Mars shows what a woman is attracted to in a man. Being with a man who is strong in her Mars element, or who makes close sextiles with her Mars, makes the relationship much easier, and increases sexual desire and compatibility. For a man, his Mars is part of his masculine nature, so it is best when his partner also relates well with this element.
Mars Sextile Moon
You will feel that you can openly express and act upon your feelings and desires, whether about love, sex, home, or family through your relationship with your romantic partner. When the Mars person is sextile to the Moon person, they will take this as an opportunity to show off their assertive side, and feel energized by your relationship and having you as a partner who is receptive to his lead.
