Venus-Mars interaspects:

Even better is when you have a “double-whammy”; when your Venus aspects your partner’s Mars, and when your partner’s Mars aspects your Venus. Venus is the planet of love, affection, and romance, while Mars is the planet of raw sexual energy. Together, they make fireworks!

The Mars person feels adored and loved by the Venus person, and finds them beautiful. The Venus person is energized and sexually stimulated by the Mars person. When this interaspect shows up in synastry, true sexual compatibility is indicated.

This is especially true of the conjunction, sextile and trine. In these cases, sexual energies and attraction are indicated on the part of both parties. In the case of the square and opposition, attraction and great sex are still indicated, but the Venus person may find the Mars person overly aggressive and may feel the Mars person is only interested in sex. Conversely, the Mars person may find the Venus person too stuffy or flowery.

Mars-Mars:

I cannot stress the importance of having compatible Mars signs, when it comes to great sex! When two peoples’ Mars planets are in harmonious aspects to each other, your sexual energies match well. You like the same things sexually, and it is easy to please one another. Things just feel “natural” with this person. The square and opposition can be tricky, as it indicates discordant sexual styles. However, if there are supportive aspects, the square and opposition can still work.

Sun-Mars:

Both the Sun and Mars are masculine signs. When they make an aspect in synastry, sexual compatibility is indicated. Your body rhythms match well, and you naturally know how to please one another. Mars is especially sexually attracted to the Sun person, and the Sun person’s sexual desires are stimulated by the Mars person.

This aspect represents considerable attraction to each other’s bodies. This is especially true for the conjunction, trine, and sextile. The opposition and square can lead to conflict and ego clashes, but attraction is still indicated.

Venus-Pluto:

This is one of the hottest sexual synastry aspects two people can have! Pluto represents sex, obsession, and intimacy, while Venus represents love, beauty, and affection. Together, this spells g-r-e-a-t s-e-x! You stimulate each other’s desire to experience the depths of sexual intimacy. Physical intimacy is especially important with this interaspect; you feel a strong desire to be physically close to each other. In fact, you may find you become obsessed with one another! This aspect also indicates power struggles and domination, especially on the part of the Pluto person.

The Pluto person feels a strong desire to “merge” with the Venus person. Pluto finds Venus beautiful and intriguing. Venus is strongly sexually attracted to Pluto, as Pluto puts her in touch with her primal, sexual feelings. This is especially true of the conjunction. The trine and sextile indicate intense, but pleasing and harmonious sexual interactions.

These aspects deepen the intimacy shared by the couple, but not in an overly obsessive or destructive way. In the case of the square and opposition, strong sexual energies are also indicated, but this may be accompanied by an unhealthy desire to control one another through manipulation, jealousy, and possessiveness. The square and opposition can also indicate sexual and financial exploitation, as well as abuse. Nevertheless, Venus-Pluto in synastry is just plain hot.

Moon-Mars:

In synastry, this is a sign of true sexual compatibility. The attraction is instinctive in nature. This aspect is considered best when the woman is the Moon person, and the man is the Mars person. Like Venus-Mars interaspects, Moon-Mars interaspects represent the yin/yang or male/female energies between couples. The Mars person can instinctively sense the needs of the Moon person, and strives to fulfill them.

The Mars person is attracted to the Moon at a very basic level; he finds her basic femininity very sexually appealing. The Moon person is “turned on” by the Mars person’s advances. The attraction is very primal in nature. Together, they fuse emotionalism and feelings into sex, which can be highly satisfying for both parties.

I believe all Moon-Mars contacts, whether hard or soft, brings this energy into the partnership. However, the hard aspects can manifest outside the bedroom as emotional arguments and hurt feelings, while the softer aspects indicate supportive energies between the two.

Mars-Pluto:

This synastry aspect is HOT! It indicates overwhelming passion and intensity, due to a raw sexual energy which permeates between the couple. With this aspect, sex is intense and transformative, and the need to be physically close to each other is paramount. The sexual magnetism to each other is strong. One of you might be very physically demanding of the other, which could give rise to conflict and power struggles.

Mars Conjunct Pluto Synastry

Mars conjunct Pluto synastry creates an intense and magnetic attraction between two people. The connection is often immediate and difficult to ignore, with a strong physical and sexual chemistry that can feel consuming.

The Pluto person intensifies the Mars person’s desires, while the Mars person activates Pluto’s passion and instincts. Together, these two people can bring out each other’s confidence, ambition, and deepest desires.

This aspect often creates a relationship that feels transformative. The couple may feel more powerful together than they do separately, inspiring each other to pursue goals and overcome challenges.

However, the intensity of this aspect can also create power struggles. Both Mars and Pluto are strong-willed energies, and neither naturally enjoys being controlled. Arguments can become heated because both people may push each other’s buttons and trigger strong emotional reactions.

Jealousy, possessiveness, or competition can become issues if the intensity is not handled consciously. The Pluto person may want deeper emotional control or complete transparency, while Mars may resist feeling restricted.

At its highest expression, Mars conjunct Pluto creates a relationship where both people empower and transform each other. At its lowest expression, it can become a battle of wills.

Mars Sextile Pluto Synastry

Mars sextile Pluto synastry creates powerful chemistry while allowing the intensity of Mars-Pluto energy to flow more easily. The attraction between two people is strong, but there is usually more cooperation and less conflict than with harder aspects.

The Pluto person inspires the Mars person to pursue deeper ambitions, while Mars encourages Pluto to take action and express desires more openly. Together, the couple can accomplish a great deal because they motivate and strengthen each other.

Sexual chemistry is often intense and passionate. The relationship may feel deeply connected, with both people experiencing a strong sense of trust and fascination.

This aspect supports personal growth because each person encourages the other to evolve. Challenges are more likely to be faced as a team rather than becoming a competition.

Mars sextile Pluto creates a bond where passion and transformation work together in a constructive way.

Mars Trine Pluto Synastry

Mars trine Pluto synastry indicates strong attraction, passion, and a powerful sense of connection. The two people often feel energized by each other’s presence and may experience a deep physical and emotional bond.

The Mars person brings motivation, courage, and action, while the Pluto person adds intensity, depth, and emotional transformation. Together, they can inspire each other to grow stronger and pursue their goals.

Sexual chemistry is typically very strong with this aspect. The attraction may feel instinctive, passionate, and deeply satisfying because both people naturally understand each other’s desires.

Unlike the harder Mars-Pluto aspects, there is usually less struggle for control. Instead, both people can use their combined energy to support one another and overcome obstacles.

This aspect often creates a feeling that the relationship has a powerful purpose. The couple may feel stronger together than they do individually.

Mars trine Pluto is one of the more harmonious ways to experience the intensity of Mars-Pluto energy.

Mars Square Pluto Synastry

Mars square Pluto synastry creates an extremely intense connection filled with attraction, passion, and emotional challenges. The chemistry between these two people can be undeniable, but the relationship may also bring out powerful reactions.

The Mars person and Pluto person strongly affect each other, often triggering emotions and desires that are difficult to ignore. Both people may feel fascinated by one another while also feeling challenged or threatened by the other’s intensity.

Power struggles are a major theme with this aspect. Mars may feel controlled or manipulated by Pluto, while Pluto may feel that Mars is too impulsive or unwilling to compromise. Both individuals may try to assert dominance, leading to arguments and conflict.

This aspect requires awareness around anger, jealousy, and control issues. If unhealthy patterns develop, the relationship can become emotionally exhausting or destructive.

However, Mars square Pluto can also be deeply transformative. When both people learn to respect each other’s power and avoid trying to dominate one another, this aspect can create incredible passion, resilience, and personal growth.

Mars Opposite Pluto Synastry

Mars opposite Pluto synastry creates a powerful attraction combined with a strong potential for conflict. This aspect often feels magnetic, intense, and impossible to ignore.

The Mars person is drawn to Pluto’s depth and mystery, while Pluto is attracted to Mars’ confidence, energy, and directness. There can be a feeling that the two people awaken something powerful in each other.

However, oppositions create tension, and Mars-Pluto tension can manifest through competition, control issues, or emotional confrontations. Both people may feel challenged by the other and may struggle with who has the upper hand in the relationship.

The Pluto person may want complete honesty and emotional transparency, while Mars may prefer a more direct and independent approach. Differences in how each person handles vulnerability and control can create conflict.

Like all Mars-Pluto aspects, this connection carries transformative potential. The relationship can force both people to confront their own fears, desires, and patterns.

When handled with maturity, Mars opposite Pluto can create a deeply passionate bond where both people inspire growth and change. Without self-awareness, however, the intensity can become overwhelming.
