Did you notice any yellowish powder (the pollen) come off the plants at all? You have to be very careful to try not to shake the male plant. If shaken too much, pollen will be released...only time will tell.

To aviod any more possible pollenation though, wash your hands, change ALL of your clothes that you were wearing when you removed the males, before you enter your GR again. Make sure there is no cross contamination.

Now, off with their heads!!
