Y'know I am amazed.
But this is exactly the same result Penn and Teller got in one of their Bullshit episodes where they were testing sexuality against twins. Pretending to be doing a screen test for a soap opera, they were spraying these two blokes with different hormones and musks to see which of these identical shirtless buff firemen would pull a greater response from the female actresses who got to be held so tightly into these huge welcoming oiled guns.
Just amazing.
