I have always been interested in whether or not bisexuality can be detected in the astrological natal chart. The reason is somehow I attract these people into my close friendship. For some reason, I do not totally agree with certain research that have been done on the subject. I am Venus/Mars Conjunction in Gemini in 12th house, my Venus is Trine Uranus, Uranus opposition Chiron and Chiron Trine Lilith and Vesta. Regardless of what astrologers suggest, I am extremely straight, but I like queer men. This somehow works for my energy and spiritual growth the best. I find that bi men are more attentive, tender and loving for some reason.

I believe my Venus/Mars Conjunction Trine Uranus gives me an unconventional attitude to relationships as well as relating in to people in general; my need for personal freedom and personal space (Uranus) has to be blended somehow with the desire to unite and share with another (Venus). I face a freedom and closeness dilemma, which is at the core of Venus/Uranus aspects. To me the quality of relationships is really important, while physical expression is less relevant.

I personally accept that sexuality in men can be very fluid. Men need to experiment and get adrenaline into their blood.

Sexual preferences has changed dramatically during the last century. So there is absolutely no doubt that Uranus, Neptune and Pluto play a major cause of sexual preferences in a horoscope. As these planets corresponding to in a natal chart, are the planets responsible for the manifestation of collective unconscious, so their influence distort natural manifestations of Mars or Venus. In particular, the adverse effects of higher planets form a basis for compulsion, as well as for a formation of peculiarities.

It’s still a mystery how sensibility works in likes and dislikes.

Uranus makes people experiment and try something new. A strong or broken Uranus produces interest in things that are opposite to everyone else. Uranus is fully connected to all eccentricities, bisexuality, and even some manifestations of fetishism.

With a strong aspects between Uranus and Venus, eccentricities can manifest in all its spectrum.

Damaging Uranus in a horoscope is common in people whose sexuality is fluid.

Neptune behaves as a female planet. Neptune is associated with such deviations like masochism and fetishism. In addition, in the women’s horoscopes Neptune relationship with Mars increases sexual potential, while in man’s horoscopes Neptune with certain aspects with Mars appears frequently as a distortion of sexuality. Strenuous bond Mars-Neptune is one of potential characteristic signatures at male deviations.

Pluto is an active, strong and destructive planet. Pluto also has a direct relation to an experience of violence.

In male horoscopes, Pluto’s link with Mars increases sexuality potential. While in a female horoscope, Pluto appears more likely as a distortion of a sexual experience. In particular, in female charts, a tense aspect of Mars-Pluto, especially “tied” to one of female planets is a classic pointer of physical danger from men in certain periods of time. – Definitely there is a link, if a girl was treated badly as a child by a male figure, or her father, this can be a cause of distortion of sexual experience later in her life.

If Venus is damaged by aspects to higher planets, especially to Uranus and Neptune, this could be an indication of personalities who have specific or atypical sexual preferences.

A person after psychedelic therapy suddenly remembered a reason for his aversion to feminine, repressed from consciousness. Realization of such an error can be stunning and later may have an enormous impact on future.

Other pointers of bisexuality in a horoscope

Men

Strong planets are Moon, Venus, and Sun, and simultaneously weak planets are Mars and Saturn

Women:

Strong planets are Mars and Neptune, and simultaneously weak planets are Venus and Moon

Accented signs: Cancer, Libra, Aries, Aquarius, Taurus.

Aspects: Bad configuration between the planets: Sun-Mars, or Sun-Moon-Venus-Mars.

Venus on the Ascendant or the negative aspects with Sun, Mars, or Moon.

In matters of sexuality, Lilith acts as a catalyst for all emotional processes. Lilith is capable to intensify our involvement in any emotional processes. Lilith acts as a catalyst and motivator of sexual fantasies:
1. Position of Lilith is in Scorpio, Aries, Leo, Pisces, Capricorn, Aquarius, and Taurus
2. Position of Lilith is in I, V, or VIII houses.
3. Lilith has an exact conjunction or harmonious aspects with Venus, Mars, Sun or Moon.

Gay men, inclined to a passive role, really can have well-aspected Moon and Venus; at the same time, they should have weak and damaged sun, Mars and Saturn. 

Active type is a hypertrophied man with accentuated masculine planets. and especially strong Mars.

Homosexuality could lie in an integration of deep unconscious complexes that relate to influence of higher planets.

According Ptolemaeus, the passive type must have a strong bond Venus of Mars, with the absence of deterrent effect of Saturn. With a morning Venus and nighty Mars, or vice versa, native will be happy to have sexual contacts with both sexes. If evening Venus and Mars in female signs of astrology, it gives a native tendency to a passive role, but if both Venus and Mars are morning planets – it gives a native an active role.

There are other indicators of non-traditional sexuality in a horoscope.

• Uranus is in a sign of Venus, or Mars is damaging a significator of the 1st house.
• Uranus is in a hard aspect with Venush or Mars with a proviso that one of these planets is related to the 1st house – gives a quite expected signature of bisexuality.
• In horoscopes of bisexual men expect Venus be in Aries or Virgo – those are most common placements. But Scorpio appears to be well within an average waiting range. Venus in Sagittarius is a rare visitor.
• Mars in horoscopes of gay men most often found in Cancer and Virgo, but very rarely Mars can be found in Sagittarius, Capricorn or Libra. In addition, Mars is usually retrograde – much more often than in heterosexual charts. You also find Mars burned.
• From the leading aspects, Venus is square or opposition to Neptune; Mars is square to Sun, Saturn; or Mars in opposition to Jupiter or Neptune; or Mars is in conjunction, sextile or square to Uranus. In addition, Mars or Venus must have a connection with ASC, so gender issues would become one of a leading characteristics of personality.

There is an interesting fact that natal charts of bi are associated with the VII house. Other contributing factors are Neptune or Uranus in VII house or damaging Neptune and Uranus; when Lilith is connected with VII house or its ruler; as well as Mercury in the VII house or in aspect with the ruler of Dsc.

Also another possibility of bisexuality in a horoscope is in a chain of dispositions – Venus and Mars should be in mutual reception and Pluto must be retrograde.

Mercury is a sexless planet. Mercury plays an important supportive factor in charts of people with non-standard sexual orientation.

People I know:

Venus conjunct Uranus in Sagittarius.

• practice sexually open / non-traditional relationships.
• partners of different ethnic backgrounds, due to Venus/Uranus aspect.
• Sagittarius with many planets in general and Venus/Uranus can indicate LGBT orientation, but it could also just signify non-traditional preferences in some other way.
• those with sagittarius ♐️ moon 🌙 and a lot of sagittarius in their chart tend to be more fluid in their sexuality
• Venus in Sag will lead to exploration and excitability, not preference or identity, a possible predisposition to expansion in the arena of values.
• Libra/Aries has been known to harness yin/yang qualities.
• Mars – Venus placements as well as the 8th house.
• my experience: Mars – Venus located in dualistic signs (Gemini) indicate LGBT tendencies while Uranus in the 8th house often indicates sexual fetish and kinks such as BDSM, cosplay or anything out of the ordinary style.

People who has these degrees to are not necessarily bisexual, but have a predisposition to it.

Bi horoscopes usually heavily filled with a sign of Cancer with a presence there a Moon; or a square to Moon or Venus, or square to Venus, and has major aspects to Pluto, or Cancer rising in a male horoscope.

In addition, connection of Spica and Arcturus with planets such as Venus, Mars, Sun, and Mercury – gives a tendency to bisexual love.

People with Venus on the Asc were “seen” in bisexual relationships.

Manubrium (Manubrium – Latin “handle”.) –
I. The fixed star, Omikron 39 of Sagittarius. Apparent magnitude 3.77m.
The figure constellation M. is on the head of Sagittarius (together with the stars of Sagittarius and head Albaldah). According to Ptolemy, this star provides astrological influence, similar to Sun and Mars. According to Deborah this star indicates a brave, heroic and reckless character, as well as a possibility of blindness from fire or explosion.

According to tradition of Avesta, servants of Manubrium are Venus and Pluto. This star sometimes is associated with sexual perversions, child molesters, rapists, seducers, playboys.  If this star is on the cusp of the XII house, and also in conjunction with Venus, a person can be a victim of rape, or  mockery of sexual maniac.

Sexual orientation like religion and gender likely cannot be detected in the chart. It can show only probability.

Obviously one can say that such research on sexual preferences is homophobic because we fear of homosexuality for very personal reasons. God forbid to fall in love with a person who technically cannot fuck you, and you obviously look for ways to turn their interest. Of course, meditaton helps because we can go beyond orgasm.
