Seeing as corn is pollinated by the wind, a "male" corn can mate with many, possibly hundreds of "female" corns.
On a side note: Male corn snakes, can typically service 4-6 females. Possibly more if he is given sufficient time to rest between "jobs." He should do the deed with just about any female that is willing and presented to him (not unlike the typical male college student, myself being atypical.) Just as long as he is getting enough rest time and is eating he could hypothetically go on forever.
