The Coolidge Effect

[virginjohn]

I came across this on wikipedia:

In biology and psychology, the Coolidge effect is a phenomenon—seen in nearly every mammalian species in which it has been tested—whereby males (and to a lesser extent females) exhibit continuous sexual activity if they are introduced to new receptive sexual partners, but will eventually stop having sex if the partner has already been copulated with.

Now the best part is that the name was based on

... an old joke about Calvin Coolidge when he was President … The President and Mrs. Coolidge were being shown [separately] around an experimental government farm. When [Mrs. Coolidge] came to the chicken yard she noticed that a rooster was mating very frequently. She asked the attendant how often that happened and was told, “Dozens of times each day.” Mrs. Coolidge said, “Tell that to the President when he comes by.” Upon being told, President asked, “Same hen every time?” The reply was, “Oh, no, Mr. President, a different hen every time.” President: “Tell that to Mrs. Coolidge.”

Thanks for this, "virginjohn". Makes the point the way one would have expected Calvin Coolidge to and made me chuckle besides.
