I have no experience with them, but I do with king snakes, & they have a similar propensity; anyway, I wouldn't let down your guard when breeding them, just as with kings. One way you can gauge their interest & get them used to the other's scent safely before a meet-up is to put each one in the other's cage without the occupant being "at home"- just for a while, so they get each other's scent...it can help them get "in the mood" to breed for when they finally meet "in person".
