With corns, the entire process takes 20 to 30 minutes tops; especially for two that are ready to go. Have you brumated yours yet? After brumation, they're usually primed up and ready to go. Usually within a few minutes of putting them together you will see courting (the female will start "twitching" showing she's receptive, the male will start positioning himself). I place them in a separate tub with news paper so I can check for "evidence" of successful copulation.

If I don't see anything right away, I'll leave them together for a couple of hours and then separate them and look for evidence. If there isn't any I give them a week off and try again. If there is, I wait three days and repeat for a total of 3 copulations. Then its waiting time for eggs/hatchlings.

They're a lot easier to breed than the bps.
