Their is an instinctual desire, not sure of the clinical term, but it's along the lines of "sperm competition." Our anatomy is designed to promote the fittest sperm reach the egg. The head of a male penis is designed to work as a suction device and pull out competing sperm prior to the next male depositing his load.
If you'e not cuck, like me, it makes for some AMAZING sex after she is done with a different partner.
