Sounds as if you are being a pest in their world,dont sweet the sperm sickles
and minor debris. Let them go at it as hard as they can,for as long as they can.
Get them together ASAP and leave them till you see the male ignore her for several days
Clean their cage and introduce them again for a few days just to make sure.
Snake porn can not be scripted,they know what they need
You piddle dinking over small stuff will cause set backs that abit of patience could have avoided.
Congrats on the progress made. . . . .
