Bisexuality in Astrology: Signs, Planets, and Birth Chart Placements

Bisexuality in astrology is associated with mutable signs, especially Gemini and Pisces, strong Venus-Uranus aspects, and an emphasis on the 5th, 7th, or 8th houses. These placements are linked to curiosity, attraction to more than one gender, sexual experimentation, and relationships that break traditional expectations.

I’ve noticed that Gemini, Aquarius, and Pisces placements come up a lot in charts of bisexual people, especially if Venus or Mars is involved. Mercury is interesting, too, because it’s traditionally considered an androgynous planet. Uranus adds another layer, particularly through aspects to Venus, Mars, or the Moon.

Venus or Mars in Gemini

Gemini is represented by the Twins and ruled by Mercury, the planet associated with androgyny and duality. It’s probably the first sign I’d examine in a chart with strong bisexual themes.

Venus in Gemini can indicate attraction to more than one gender, especially people with an androgynous appearance. Someone with this placement might love feminine men, masculine women, or people whose style mixes traditionally masculine and feminine qualities.

Mars in Gemini is curious about sexual experiences. These people may have a wide range of physical preferences, and their attraction can change depending on the person they’re interested in.

Gemini Venus can also enjoy experimenting with personal style, including gender-neutral clothing and androgynous aesthetics.

Venus or Mars in Aquarius

Aquarius Venus and Mars are two placements I’d definitely check. Aquarius is ruled by Uranus, a planet associated with unconventional relationships, individuality, and breaking social expectations.

Venus in Aquarius can be attracted to people regardless of gender, especially if there’s a strong friendship or intellectual connection first. Someone’s unusual appearance or refusal to follow gender stereotypes might make them even more attractive.

Mars in Aquarius can be sexually adventurous and curious about experiences outside traditional relationship expectations.

An Aquarius stellium, particularly one involving Venus, Mars, or the Moon, adds to this theme.

Venus in Pisces

Pisces Venus is another placement I’ve noticed in LGBTQ+ charts. Pisces is romantic, imaginative, and interested in emotional closeness.

Someone with Venus in Pisces may fall in love with a person’s personality and emotional presence before becoming interested in their physical appearance. They might date men, women, or nonbinary people because the connection itself is their biggest attraction.

A Pisces stellium can indicate similar experiences, especially with Venus or Mars involved.

Venus or Mars in Sagittarius

Sagittarius loves exploration, variety, and people from different backgrounds. With Venus or Mars here, attraction can extend beyond the person’s usual preferences.

Venus in Sagittarius may be interested in partners of different genders, cultures, or lifestyles. Intellectual chemistry and shared adventures can be especially attractive.

Mars in Sagittarius adds sexual curiosity and an interest in experimenting. Someone with this placement may explore their sexuality through different relationships and experiences.

Venus or Mars Aspecting Uranus

Venus conjunct, square, or opposite Uranus is a particularly interesting combination for bisexuality. Venus represents romantic attraction, and Uranus is associated with unconventional desires.

Someone with Venus-Uranus aspects may be attracted to people who challenge their usual type. They might have dated men for years and suddenly develop a strong crush on a woman, or vice versa.

Mars-Uranus aspects can describe sexual experimentation, unusual preferences, and an attraction to people who break gender stereotypes.

Trines and sextiles can express similar themes through a more comfortable approach to exploring attraction.

Mercury Conjunct Venus or Aspecting Mars

Mercury is traditionally considered androgynous, so its connection with Venus or Mars deserves attention.

Mercury conjunct Venus can indicate attraction to androgynous people or an interest in presenting oneself through a mixture of masculine and feminine styles.

Mercury aspecting Mars can bring curiosity into sexual experiences. These people may enjoy exploring different expressions of attraction and discussing sexuality openly with their partners.

Aquarius Moon and Uranus Aspects

Aquarius Moon is another placement worth examining, particularly in the charts of bisexual women.

The Moon represents emotions, femininity, and personal needs. Aquarius adds an unconventional approach to these themes.

A woman with an Aquarius Moon may be attracted to women who express femininity differently or prefer relationships that challenge traditional gender roles.

Moon conjunct, square, or opposite Uranus can introduce similar themes, especially an interest in unconventional partners and relationship dynamics.

Mars or Venus Aspecting Neptune

Neptune is associated with fantasy, imagination, and attraction that crosses conventional boundaries.

Venus-Neptune aspects can indicate romantic interest in people of different genders, especially if emotional chemistry develops first.

Mars-Neptune aspects bring fantasy into sexuality. Someone with Mars conjunct or square Neptune may be curious about experiences involving different genders or attracted to partners with an androgynous appearance.

The 5th, 7th, and 8th Houses

I’d also examine the signs on these three house cusps:

5th house in Gemini, Pisces, or Aquarius: Curiosity about different romantic experiences and types of partners.
7th house in Gemini, Pisces, or Aquarius: Attraction to unconventional partners or relationships involving more than one gender.
8th house in Gemini, Pisces, or Aquarius: Sexual experimentation, fluid desires, and curiosity about different intimate experiences.

Mercury or Uranus in these houses is worth examining, too, particularly through aspects to Venus and Mars.

Gemini, Pisces, or Aquarius Stelliums

A stellium places several planets in the same sign, making that sign’s characteristics particularly prominent.

Gemini stelliums can indicate curiosity about different genders and attraction to androgyny. Pisces stelliums emphasize romantic and emotional attraction, and Aquarius stelliums can bring an interest in relationships outside traditional expectations.

I’d give extra attention to stelliums involving Venus, Mars, Mercury, or the Moon, especially if those planets also aspect Uranus or Neptune.

Uranus on the Descendant or Aquarius Descendant

Uranus conjunct the Descendant or Aquarius on the 7th house cusp can indicate attraction to unconventional partners, including people of different genders. Someone with these placements may be drawn to androgynous people, bisexual partners, or relationships that challenge traditional expectations. Uranus on the Descendant can also bring unexpected romantic attractions, including falling for someone completely outside their usual type.
