Mars in the 8th House

Sample from our LoveStyles report: You have very strong desires, and once you decide to possess something, you usually succeed in doing so. You may experience shortages of love and money to encourage you to be less possessive in these areas of your life. You have the ability to see through the false pretenses of others. On the level of karma, you can make up for past lives of greed and abuse by sharing your resources with others in need. There may be some sexual trauma in your early life that you struggle with as an adult.

With Mars in the eighth house, shades of the sign Scorpio can be found in your desire nature. You may not experience true passion until later in life, but when you do, it is magical and infectious. You have some fears of betrayal and loss that compromise your trust from time to time.
