Well in his case it wasn't just the dick itself. Women were "disgusting". So the dick needed to be attached to a manly man.
What exactly is gay? To me it's when a manly man likes manly men.
If you'd fall in love with a woman and THEN see her male genitals, it wouldn't be gay. She just was an ass to not tell you earlier 😁
If you'd see both genitals or none, it wouldn't be either. And yes, there always have been those with both or none.
