Sexually, Mars influences how you go about initiating a night of amour. Mars determines how you court a potential lover, from being coolly detached, to becoming ablaze with ardent intensity, and every style in between.
The planet is named for the God of War, but Mars energy only becomes a negative force when it serves the Ego, and not a higher cause. On a social level, it is a primal force that can become destructive when its collective power is harnessed for questionable purposes. Your Mars, or desire drives, can be co-opted and channelled by others. That makes a strong case for understanding your desires, and not allowing them to fall into shadow.
When Mars is "afflicted" or has many conflicts in a birth chart, it can lead to repressing the vital fire within. But not to be denied, a stifled Mars will eventually erupt, and emerge through temper tantrums or just a low grade, but constant irritability.
All Mars asks is to be channelled and given an outlet. When your own Mars nature is understood, it's easier to master. It guides you toward making the most of your potential through the use of your own natural assertiveness. (Source: astrology.about.com)
