Zodiac Sexual Compatibility

In Western astrology, intimacy is read through the elements: signs of the same element pair most easily, then fire with air and earth with water, while chart astrology gives a Venus and Mars contact more weight than the Sun sign alone.

This page is written for adults. It describes, in plain and neutral terms, what a tradition or a body of research says about intimacy between partners. It says nothing about any one couple, it is not medical or sexual health advice, and no decision about a real relationship belongs to a web page.

What is zodiac sexual compatibility?

Zodiac sexual compatibility is the tradition's reading of physical and romantic chemistry between two sun signs, and like every sun-sign reading it works through element groups. This site uses the same rating for intimacy as for love, and the zodiac compatibility calculator gives it for any two signs. Sex compatibility by zodiac sign, sexual astrology and the zodiac sexuality compatibility chart all point at that one rating: the zodiac chart shows it for every pair, and there is no separate chart for intimacy.

Nothing here measures two people. Astrology is regarded as a pseudoscience, and the best-known controlled test, published in Nature in 1985, found that astrologers could not match birth charts to personality profiles better than chance.

Which zodiac signs are most compatible in bed?

In the tradition, signs of the same element. The star signs it reads as best together fall into three groups, in this order:

1. The same element: fire with fire, earth with earth, air with air, water with water. The tradition reads a shared pace and temperament: two fire signs share drive, two earth signs practicality, two air signs talk, two water signs feeling.
2. Fire with air, earth with water: the elements the tradition calls complementary. The tradition reads them as a match of different strengths: fire's drive with air's communication, earth's practicality with water's emotion.
3. Every other pairing: fire with earth or water, air with earth or water. The tradition reads more difference between the two, and so more to talk through and adjust to. It does not read these pairings as closed, only as less effortless.

The order describes elements, not people. No sign is read as more or less interested in intimacy than another, and the list says nothing about what any couple does or wants.

Does astrology rate sexual compatibility separately?

Not on this site. One rating serves love, friendship, marriage and intimacy, and each pair page reads that rating for intimacy in a short section of its own. The tradition itself does look further than the Sun sign for attraction, and that is where chart astrology comes in.

Does your Mars sign matter more than your sun sign?

For attraction, chart astrology says yes. It reads Venus as how a person gives and wants affection, and Mars as energy, courage and ambition, the way a person goes after what they want. Between two birth charts, a contact between one person's Venus and the other's Mars is the tradition's attraction contact, and this site's birth chart calculator puts it in its heaviest class, alongside Sun to Moon. How each Venus and Mars sign is read, and how the two meet between charts, is set out in Venus and Mars in synastry. A sexual compatibility test by zodiac sign sees only the Sun sign; the birth chart calculator, linked in the footer, places Venus and Mars for both people from two birth dates.

What does sexual compatibility mean outside astrology?

Outside astrology, sexual compatibility describes how two people's wants, pace and ways of talking about intimacy line up, which is something a sign cannot tell you and only the two people can find out together. For that wider meaning, read what sexual compatibility means.
