Maybe the problem is not with the male, but with the females who may not have released the pheromones yet to trigger male interest. Perhaps leave this male with the female you really prefer he mate with, and give them a couple more weeks at least.

Hope this works out for you. I am a total newbie with breeding mine; this is the first time for both me and my snakes.
