Venus and Mars are the sexy planets, the two people always pay attention to because of how they relate to relationships. Venus rules love, how we love and what we want in love; Mars rules drive, what gets us going, moving. Notice that Mars doesn't rule sex itself, it rules drive, therefore it rules our sex drive (sex itself is ruled by the asteroid Eros). Study the placements and aspects of each planet to gain further insight into what you need in a relationship. Just like with the Sun and Moon, the aspect they make to one another is usually the most important, and indicate how you deal with what you desire in love and sex. The midpoint (exact middle) of Venus and Mars shows how you best integrate the two, and find the perfect balance between your desire for love and drive for sex.
In prediction, the transit (moving) Venus shows where you'll experience greater ease in life. Things may develop easier. You may also experience laziness or overindulgence with the areas it's touching. The areas of life ruled by the house it's going through could also indicate how you can meet a new romantic partner. Transit Mars shows areas where you'll be most driven, and often the areas of life the house it's going through rules are the ones that are of most concern at the time (I've noticed that when I do a reading for someone, often the thing they want to know most about is ruled by the house Mars is touring).
Venus rules Taurus and Libra and the 2nd and 7th houses, Mars rules Aries and the 1st house.
