There is often no contemplation before action when it comes to this primal energy. All our sexual desires come under Mars. This is the raw physical energy as opposed to the creative energy of the sun. With good Mars placement we are assertive, directed and forthright with bad placement we an be impulsive,rash and aggressive. In your chart, Mars shows your basic animal nature, how you express anger and what gets you angry and more importantly what makes you act.
Mars Opposition Ascendant
The placement of Mars Opposition to your natal Ascendant creates a tense and volatile personality. This may be seen in yourself or projected onto your outside environment and people close to you. You like competition and challenging situations; you tend to attract people who will oppose your ideas or opinions. Your self-image is distorted and too much worth is put on outside interactions, especially with one on one partnerships. Compromise and co-operation are key themes that need learning with this position, you tend to argue first and ask questions later, and this can make you hard to get along with at times. While you may see compromise as something for the weak, it actually takes great strength of character to meet others halfway. It is often the case that we experience the difficulties of an opposition aspect through the behavior of other people, or actually seek that quality in another. This is particularly true here, since an opposition to the Ascendant places Mars on the 7th house cusp, the house of relationships. Hence, you may often attract people who express the qualities described above, who challenge you in some way, forcing you to stand up for yourself and develop your qualities of independence and self-determination.
