How long until the omnitrix decides to make some changes to base form Ben, in the interest of DNA collection efficiency, of course ——— It's gotta be sparked by something, like maybe he's jacking it and he or Gwen gets cum on the omnitrix. The potency of the genetic material available in the cum would obviously rewire it, and make Ben custom built to gathering more sperm. Obviously this happens the afternoon after he gets the omnitrix.
