I've namechanged as this might out me (no pun intended...)
To put this bluntly, I come from a very gay family. My grandparents have 3 lots of grandchildren - me and my siblings (3 of us), and 6 cousins between two of my aunties. So 9 of us together.
Out of 9 of us - 7 are gay. And I include myself in one of the two 'straight' ones, despite actually having had a (secret - my family dont know) relationship with a female when I was early 20s. I'm now late 20s and married to a man.
My gran insists that there must be a 'gay gene'
AIBU to think that this is absolute nonsense? AIBU to think that the most logical explanation - should one even be needed - is that none of us have grown up around healthy functional marriages or relationships? AIBU to think that the fact that we have all witnessed many family breakdowns and there are 2 absent fathers, is most likely the reason if there is one at all?!
I'm obviously not going to say that to my old gran, but goodness me - do 'gay genes' exist?!
