Astrologically, when it comes to understanding how we relate romantically to others, there are planets that serve as guides and sources of insight. These are the Moon, Venus, and Mars.
The moon in our birth chart represents how we care for others and how we need to be cared for, how we nourish ourselves emotionally and show our feelings.
Similarly, Venus’s position represents our desires, how we seduce someone, how we function as a couple, and how we enjoy life’s pleasures. Mars—its antithesis—represents how we conquer Venus’s desires, our passion, and how we put our sexual energy into action.

First, it’s important to distinguish that lunar relationships are those where we feel a guarantee that the bond won’t break—similar to close family ties or very close friends. In contrast, a Venusian relationship is about investing in a connection that we know can break much more easily than a lunar one. If we remain trapped in our lunar zone—that is, within the familiar and our comfort zone—we will never experience the magic of Venus.
When we meet someone we want to become romantically involved with, it all starts out Venusian, but at some point, it’s also important to be lunar in order to protect and nurture our connection emotionally. By connecting lunarly, that is, in an emotional way in addition to Venusian, we ensure the bond lasts.
Within a relationship, Mars needs to be balanced with Venus. If a relationship lacks excitement, a dynamic, or a break from routine, it’s because it needs action from Mars. Mars is the spark that ignites desire.
The Interaction Of The Moon, Venus, And Mars In The Birth Chart
Within a birth chart, we will have these planets in certain signs that in turn form angles with each other called “aspects”.
Let’s take as an example someone born with the Moon in Taurus, which is characterized by seeking security in relationships. In this case, this Moon is forming a square (a negative aspect) with Venus in Aquarius. When it comes to relationships, and being in this sign, the planet of pleasure not only wants to be free but also detached—showing an energy very antagonistic to Taurean attachment—creating tension between desire (Venus) and emotional need (Moon).
Alternatively, between these two planets there may be positive aspects (trines or sextiles) that help energy flow more easily, that act together when they are in the same sign (conjunction), or that there is a need for balance (opposition) when they are in opposite signs.

Let’s also take an example related to Mars, which indicates how we approach romantic pursuits. For instance, Mars in the fire sign Aries is frank and direct, while in Virgo it can be more reserved. Because it indicates how we express our libido, this planet in fire signs is extremely passionate regarding intimacy. In water signs, it behaves very emotionally, in air signs rationally, and in earth signs it is sensitively physical.
In a woman’s birth chart, the zodiacal position of the male planet Mars indicates the type of man who complements her. Similarly, Venus functions in the same way in a man’s chart. It’s also important to note that the same applies to people with same-sex attraction.
When Venus and Mars are in harmonious aspects, our desires for love are consistent with how we act to manifest them. If there are disharmonious aspects, the way we choose to fulfill our desires doesn’t align with how we actually fulfill them. In other words, there’s a tension between what we feel and how we act to obtain it.
Astrological Houses And Relationships
In addition to the combination of planets and signs, there is another dimension to consider: the astrological houses. The fifth and seventh houses encompass our relationships, with the fifth house representing romances and courtships, and the seventh house representing a relationship that has already reached the point of commitment. Both houses are defined by the sign they occupy, by the planets (if any) located within them, and by the condition of the planets that rule the signs they occupy.
Similarly, these houses are activated by transits in the sky; for example, if Venus is passing through our fifth house, it indicates that it is a good time to seduce, connect, improve our self-esteem, and focus on receiving more love.
In conclusion, to understand how we act in relation to our emotions and all that this implies in the dynamics of relationships, we must be aware that astrology has much more complex and profound components that go beyond our sun sign. To analyze a couple, there is Synastry, which is the comparison of two birth charts. There is also another technique called the Composite Chart, which is the merging of both charts into a single one—creating a map of the bond between two people.
