With Mars trine/sextile Sun, physical attraction is often felt in a lesser degree than a conjunction, opposition or square, but so as the ego clashes.

Venus-Mars Aspects in Synastry (conjunction, sextile, trine, opposition, square)
With Venus conjunction Mars, romance meets passion. Their dynamic resembles yin and yang. This kind of chemistry is hard to come by and hard to forget, therefore this is often seen as a soulmate aspect. There is an instant infatuation. Both the Venus and Mars person likes to be physically affectionate towards each other. Issues may arise from jealousy and possessiveness.
Mars sextile Venus is pleasing, romantic and stimulating. This aspect can usually be seen in a long lasting relationship, friendship or marriage due to less intensity sextile aspect brings.
With Mars trine Venus, romantic and sexual attraction is felt less intensely, but it is a very compatible and harmonious aspect. Loving connection between Mars and Venus here indicates a strong bond, where both partners feel very fulfilled in each other’s company.
Mars square Venus is more sexual than romantic. They both indulge their deepest desires through each other, but if the relationship lacks solid foundations, it can quickly crumble. Jealousy, ego clashes, emotional defensiveness are some of the common issues.
With Mars opposite Venus, there is a strong push and pull dynamic. Sexual intensity is off the charts. It is almost as if Mars wants to conquer and possess Venus. Problems often arise when Venus doesn’t go along with Mars’s war-like attitude towards love.
Mars-Mars Aspects in Synastry (conjunction, sextile, trine, opposition, square)
With Mars conjunct Mars, there is a mutual understanding of each other’s deepest, rawest desires and instincts. Even though your personalities may be different, you both feel such a strong, almost ‘’primitive’’ sexual pull towards each other. Problems may arise when egos clash and instead of solving these differences by having a pleasant debate, you choose to compete with each other.
Same intense sexual attraction goes with Mars opposite and square Mars aspects, however these relationships are harder to navigate. You enjoy pushing each other’s buttons. Cooperation and communication issues are frequent. Especially with square, the relationship is very explosive. Anger and impulse control are the biggest themes here. Both partners should learn to respect each other’s boundaries and individuality.
Mars sextile and trine Mars aspects are more balanced, though less intense in attraction. You will support each other’s goals or perhaps join forces together to pursue a common goal. There is still a combative spirit in both of you that may ignite a few arguments here and there, but with open expression and collaboration, you can turn these arguments into productive debates.
