What makes us gay?

What makes us gay?

WHAT MAKES US GAY [YOU]Lots of theories have been put forward as to why we are gay including:

  • genetic factors and brain structure
  • child rearing and overbearing parents
  • the society and culture we grow up in

Take your pick. Browse the Internet and you'll find 10 more, some bonkers. Even today, theories are fiercely debated, new ones appear, while others fall away. The nature vs. nurture argument often takes centre stage though genetic factors would seem to be the front-runner.

More importantly, perhaps, does it matter? Or as Albin belts out at the end of Act I of La Cage aux Folles "I am what I am, and what I am needs no excuses."

Genetic factors

In December 2017, the New Scientist reported reported that "...for the first time, individual genes have been identified that may influence how sexual orientation develops in boys and men, both in the womb and during life. Alan Sanders at North Shore University, Illinois, and his team pinpointed these genes by comparing DNA from 1077 gay and 1231 straight men. They scanned the men’s entire genomes, looking for single-letter differences in their DNA sequences. This enabled them to home in on two genes whose variants seem to be linked to sexual orientation."

No one chooses their sexuality

One thing we do know is that no one chooses their sexuality. It is innate and natural to us. Some gay people knew they were different, if not gay, from as young as 5 or 6 while, for most of us, our sexuality is determined by our early teens. Some men have girlfriends, get married and have families before they realise who they are  - coming out later on in their life, in their 30s, 40s, 50s, 60s, and even 70s.
