Yeah I know the difference between the two when I see them...I've been breeding for close to 10 years now. I popped him to be certain and it is a male for sure. I was told it was probed quite a few times before I got him and I got him from a friend so I rusted it. He is pretty difficult to pop though. Oh well it happens here and there...that's why everyone should sex your own snakes when getting them so its your own fault if its mis-sexed instead of someone else's down the road.
