“Baby, I'm preying on you tonight
Hunt you down eat you alive
With Mars in the 8th house, tension is raised to a higher octave. The 8th house person receives the energy of Mars, awakening a tension that cannot be denied. There is no denying of Mars energy, which in one way or another bothers the 8th house (ruled by Pluto), Mars penetrates their psyche, their innermost being. Mars unconsciously touches the depths of the 8th house person, instigates it, Mars is a powerful force entering dangerous territory, it will provoke the 8th house, awakening heavy and uncomfortable feelings in this sector.
We have two cases here: either the two are each other's worst enemies or they are completely obsessed with one another, especially the 8th house person.
Mars is provocative, it's presence attracts the attention of the 8th house, which sees in Mars, initially, someone who causes some insecurity, since it's presence is very strong for the 8th house, which is a quiet house of the water element. Over time, especially after the couple's first kiss, the 8th house will be “activated” permanently, since the 8th house cannot escape the presence of Mars, as it awakens carnal desires in the house person. It's through physical touch between the two that the connection becomes stronger, since Mars is the physical, the body. The desire of the 8th house increases as it touches Mars, which enters deeper and deeper into the psyche of the 8th house person. The Mars person, no matter how strong and determined they may be, cannot resist the 8th house, it's with the 8th house person that the Mars person will experience the most intense peaks of physical pleasure, satisfying all their carnal desires, unconsciously freeing themselves from all the emotional barriers that prevented them from fully surrendering to carnal pleasure.
Things, however, start to get out of hand, especially if the 8th house person has Pluto/8th house contacts in their personal chart. The 8th house wants to dominate the Mars person, reduce some of their “strength”, take away some of their power. Without the Mars person realizing it, the 8th house person will slowly infiltrate their psyche too. Mars becomes addicted to the 8th house, it misses the intensity that the 8th house person gives to them, what they are capable of awakening in Mars.
Generally, the Mars person “runs" after the 8th house, even when their pride tells them not to, even if they slowly feel that the 8th house person is assuming large proportions in their life, when this happens, the 8th house can feel very pleased, since they love having power over Mars, seeing how they become submissive before them.
Despite the increasing tension, despite the obsession continuing to grow, and the desire continuing to pulse at full strength, everything is wonderful when Mars and the 8th house meet physically and, possibly, emotionally. This is the wealth of Mars in the 8th house in Synastry, Mars and the 8th house are two magnetic forces, which cannot resist each other, as it's with resistance that conflicts arise. If the relationship is consensual and healthy, then there is no reason to resist: when the two bodies meet, a true treasure is formed. They are physically connected to each other, it is in the exchange of power between the two during sexual connection that unites them so deeply, it's by breaking psychic barriers, penetrating each other deeply, that the two find themselves in their soul. The 8th house, even if they don't admit it, feels the power of Mars, which, in turn, awakens their sexuality in an intense and obsessive way. Mars cannot resist the 8th house person.
The 8th house will probably go crazy about Mars, they will stalk their entire life, they will know every detail, so that they can have even more power over the Mars person. Mars likes the intense nature of the 8th house, it fuels their fire even more, but Mars does not give up their power completely, they probably resist(and even like to resist) the seduction tactics of the 8th house. But in the end the 8th house wins, mainly through the sexual encounter.
There is, however, another problem that can arise: the 8th house can use its sexual power to dominate Mars, using the intimate encounter as a form of manipulation, especially if Mars threatens to leave the relationship, or if the 8th house is jealous. There is a tendency towards possessive physical control, from both parties, but mainly from the 8th house, since it's the house ruled by Pluto and Pluto does not like to share what is his. The 8th house may think that Mars belongs to them only, especially after the relationship has already been “activated” by physical touch. Mars may run the risk of the 8th house treating them as a possession, as an object that belongs to them, which will certainly irritate Mars, who is already a powerhouse in itself. It's extremely necessary, for their relationship to survive, that the 8th house stops being so possessive and controlling and that Mars talks about everything that bothers them. If the two can work together, this is a relationship that has the potential to be unforgettable and extremely powerful and liberating.
“So what you trying to do to me
It's like we can't stop, we're enemies
But we get along when I'm inside you,
You're like a drug that's killing me
But I get so high when I'm inside you”
