It's not "just so happened." That was fully intentional.
I certainly wouldn't call it either straight or gay. i might call it bi/pan as you yourself already did, or just LGBT+.
You appear to be acting as though I don't have a comprehension of LGBT+ identities. I am an AMAB nonbinary androsexual person. It is because I understand LGBT+ identities that it is very clear to me that this isn't at all anything I would call gay.
