Mars in the 7th House

Sample from our LoveStyles report: You have tremendous sexual energy—like the Energizer bunny, you keep going and going...! You need a partner who challenges you. In fact, someone who holds his/her own in an argument turns you on. Your close personal relationships are a source of conflict in your life, and you tend to pick partners who bring out the most aggressive side of your nature. In order for your love life to be more peaceful and satisfying, you will need to cultivate the art of compromise. Avoid a tendency to jump into altercations with others without first making a genuine effort to understand their point of view.
