There are several indications in the birthchart to see & understand an individual’s sexual style.

1) Mars : Drive & action. Attraction = Physical act
2) Lilith :
Fantasies & darkside. Kink = The go-getter
3) Eros :
Turn-ons = Preferences

Often we look at Mars, but you have to consider Eros to get a full picture of the native’s sexual preferences. Mars is solely the physical act. Eros will show what’s considered a trun-on and an essential element to the whole experience of lovemaking and sex. Lilith is about our raw sexual energy and how we embrace our own vulnerable self.

The influence of Pluto plays an important role in the deeper understanding of sex to a native. To me, there are two ways of approach and understanding sex :
• The Mars-approach
• The Pluto-apporach

I may get shit thrown at me for having this opinion but the most brief explanation for Pluto having a linkage to sex is :
Sex is able to heal or destroy a person
Sex creates human life, therefore it’s a recreational act in essence
Sex can transform you permanently

Mars in Aries is known to be quick, selfcentered and loves doggytyle, but much depends on other indicators of the natal chart to see how it manifests and how the native behaves during sex. Sex is different with everyone, so a native can act differently with different sexual partners.

When Mars in Aries is receiving harmonious aspects, the sexual expression is more balanced and healthy. The person knowns what he/she wants and is secure in own sexuality. If Mars receives a lot of hard aspects, it creates difficulties in the sexuality of the native. So keep an eye on this one. Hard aspects can be overcome, but it’s very challenging for both partners if one has a difficult Mars in the natal chart.
Mars trine Saturn shows a sexual style in which the native prefers to have long sessions, slow and steady.
Mars square Neptune shows confusion around own sexual expression and could also indicate addiction.
Mars trine Uranus shows a person to be kinky and loves to try out new things,
Whilst Mars square Uranus can cause restlessness as the native is confused over what kind of kink he/she feels attracted to. a Mars-Uranus aspect is often linked to kinks.
Mars square Jupiter can indicate a person who is to fast, could be a bit impatient.
Mars sextile/trine Sun , especially in a male chart, shows a native who is comfortable with his own masculinity, his sexual expression and ego are balanced, which is very important if you ask me. Hard aspects between Mars and Sun can show someone to be competitive, which for some can be fun in the bedroom, but harmonious aspects is what i personally advice.
Mars sextile/trine Moon shows a native that acts out of emotion, one who needs feelings for arousal, usually the native is very nurturing towards the partner.
Mars in aspect to Northnode shows a high sexdrift, someone who seems to be never satisfied, especially with the hardaspects. They can experience sudden urges.
Mars conjunct Pluto shows a native to have a strong sexuality with very outspoken desires, the native needs soulconnection for arousal. Mars-Pluto can show a native to love power during the sexual act and can make one kinky aswell.
Mars square Saturn is one of the more difficult aspects to have as it brings sexual karma in most cases and restrictions in sexlife, such as attracting partners that don’t satisfy the needs, or encountering lots of obstacles within intimate relationships.
Mars square Moon shows a native to have very powerful emotions and urges, could show a native to be impatient aswell.
