Muscle Growth and/or Muscle Growth Worship is a fetish in which men and women are sexually aroused by the demonstration of strength an muscles but also the sometimes impossibly bulking of a human body.  This week I am speaking to D, who goes by Musclegrowworship (@musclegroworsh) on twitter and forums. He is a content creator and very much into the idea of muscle growth.  Don't know what that means?  Listen in, it's much more mainstream than you may think.
