Venus-Mars interaspects: This is especially potent when the woman’s Venus is being aspected by the man’s Venus. 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 potent when the woman’s Venus is being aspected by the man’s Venus. 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. When it is the woman’s Mars aspecting the man’s Venus, the man may feel the woman is too aggressive for his taste (this, of course, depends on each person’s individual chart). 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.
