What pattern of sexual behaviour, noted in males, is called the 'Coolidge effect', being so named after some remarks of President Coolidge and his wife?

Please don't let the answer be "Rubbing Vaseline on one's head while eating breakfast."

The answer could be quite long. This site explains the "remark" of the Coolidge's and the "Coolidge effect" for both sex.

from Wikipedia -

In biology, the term Coolidge effect describes the re-arousal of a male animal by the introduction of a new female.

Some researchers think that exposure to the pheromones of a new female is a significant factor in this phenomenon.

The term comes from an old joke according to which President Calvin Coolidge and his wife visited a government farm one day and were taken around on separate tours. Mrs. Coolidge, passing the chicken pens, inquired of a supervisor whether the roosters copulated more than once a day.

"Yes," the man said. "Dozens of times." "Tell that," Mrs. Coolidge replied, "to the President!"

Some time later the President, passing the same pens, was told about the roosters - and about his wife's remark. "Same hen every time?" he asked. "Oh, no, a different one each time," the supervisor replied. "Tell that," Coolidge said with a sly nod, "to Mrs. Coolidge."

I am so glad it had nothing to do with rubbing Vaseline on someone's head while he eats breakfast. Yes, this was a favorite of Coolidge's.
