Origin of sixty-nine

  • From the resemblance of the figure 69 to the position assumed by the two people

    From American Heritage Dictionary of the English Language, 5th Edition

  • From the rotational symmetry of the numeral 69 - if rotated a half-turn (by 180°), the numeral remains the same, and a couple both giving oral sex at once have, in principle, a similar rotational symmetry.
