We take sex for granted — it got us all here, after all. But, it isn't the way of life for everything. Sex, as humans and other animals do it, is bizarre.

President Trump signed a bill to extend current levels of government funding after funding expired briefly, White House spokesperson Judd Deere confirmed early Thursday.
