Is it a penis, or is this just the human nature to look at something and say "haha that looks like a penis"? Because frankly, if any of y'all's genitalia looks like that I'd recommend you consult with your physician.
It's not even like the object screams 'sexual organ'. Boston University archaeologist Curtis Runnels, who was not involved in the recent study, told Science the ornament looks "rather shapeless", and at first glance, it's hard to disagree.
