Homosexuality is a subject that hasn't been covered in vedic astrology that much. There is not much data or research to go through when judging homosexuality in a chart. But in modern era homosexuality is no longer a crime. Today westerners have legalized it while many forward thinking Indians have accepted that gay relationship isn't a crime.

Mercury seems to be the catalyst who drives gay relationships. Of all the famous celebrities from LGBT Community most of them have Mercury with ascendant lord or seventh house lord which drives them towards homosexuality. Unfortunately there isn't much data to go by. There is only moon charts of famous celebrities from LGBT community. But one pattern seems to be that Mercury is involved.

Mercury in vedic astrology is a prince. Mercury is royalty without responsibility. Mercury is chatty, articulate and has a curious personality. Mercury is open to trying out new things and is not bound by societal norms and dictats. Mercury can be drawn towards same-sex relationship out of genuine curiosity of exploring what is generally forbidden by society.

Venus and Rahu both share Mercury's beliefs of trying the forbidden and taboo sexual activities. And they are far more likely to try sexual experiments in bed including BDSM, sodomy and same sex relationship. Problem is Venus and Rahu seek societal acceptance and may not come out openly homosexual in places where gay relationship is still a taboo. Many times individuals with prominent Venus or Rahu are influential classes in society who practise all sorts of sexual experimentation behind closed doors. But such individuals are less likely to be open about their sexual preference.

The circumstances for gay union are not really different from those of heterosexual couples. Jupiter or Rahu placement or aspect on house of marriage or a favorable vimshottari period is the driving factors to seek gay union.

Ofcourse a few celebrity couples and horoscope are not enough to derive a pattern. Many horoscope charts and data from it need to be analyzed to get clear patterns and also get more information on those seeking gay union. If and when those are available a new article perhaps with much more clarity would be made available.
