What if the person in question is a lesbian?
Sun and Mars still apply? OR Venus and Moon?
Good question, Bunraku. This may be a case in cis and hetero women's charts, but I am genderfluid and identifies as both male and female, and is gynephile (attracted to females), would Jupiter be in my natal chart on the ideal woman, and in my natal chart, it's conjunct Mars and Saturn (and Lilith) in my 3rd-sign of Virgo. For women whether they're cis and trans, and straight or LGBTQ, the planets Mars and Jupiter represent a lover of any biological sex and/or gender.
My half-sister born on Dec 21, 1970 with a Libra moon, Leo-Virgo ASC (the 29' Leo associated with riches she has and the Virgo rising is terrible) and worse of all, a Mars scorpio. She's half a Capricorn going by her winter solstice birth (San Francisco, CA, USA). And still, I can get along with many Sagittarius people...with a few issues (the so-called "sex-tile" for most solar Aquarians).
An ideal mate is Sagittarius rising (is Jupiter in there?), Cancer sun (my rising), Virgo saturn (Aquarius' ruler - my sun sign) and Aquarius moon (conjunct my sun). Years with Jupiter in its ruling sign Sagittarius are 1971 (older than me - she is mature and experienced) and 1983 (slightly younger than me - average gap of age between males and females in marriage); and esp. Jupiter conjunct saturn (1979-80) but there's my natal Mars caught between Jupiter and saturn.
