We all read about how Venus is love, Mars is sex, the Moon is emotional needs, and so on, but they're all about telling you the kinds of traits you should look for in a mate rather than the actual zodiac signs you'll like. These 3 placements can show the actual signs you like and attract to you.
Jupiter is the happy planet, and it shows areas of life we have the easiest (and sometimes luckiest) times with. Your Jupiter sign can also tell you one of the signs you'll like most. This applies not only to Sun sign, but anyone with an Aquarius personal planet (Sun, Moon, Mercury, Venus, Mars). With rising signs, I've found that you may actually like the opposite sign rising because then their 7th house is in your Jupiter sign, putting Jupiter on the house cusp or in the house. The 7th house rules our relationships. Jupiter in play helps you to genuinely like the other person.
The Sun-Moon midpoint is the exact middle between your Sun and Moon. It shows how we integrate our ego (Sun) with our emotions (Moon), and how we feel most "whole." So it makes sense we'd be attracted to the sign of our Sun-Moon midpoint, because their qualities are ones we want in our own lives (because their qualities integrate our Sun and Moon). The Sun-Moon midpoint can be a sensitive point, so anyone who triggers it for you can activate the energy.
Your North Node is one of the lunar nodes, on an axis with the South Node. The North Node is a spiritual point, showing the attributes you should aspire to integrate into your life to further yourself as a person. If someone's Sun or other personal planet is in the sign of your North Node, they're pulling you forward in this life, forcing you to grow. If you're not ready, it's an unsettling experience. If you are ready, they're the best relationships you'll have. No matter what, you can't go into things with someone who hits your North Node lightly.
RECAP: Find those who have a personal planet (Sun, Moon, Mercury, Venus, Mars) or Rising/7th house in your Jupiter sign, Sun-Moon midpoint sign, or North Node sign
