I had someone show me how to pop and probe cornsnakes. Both are mega easy to do, but are something you should really have someone show you.

Anyways, well I tried to pop my pastel male and couldn't get anything to pop. I don't doubt the sex as it's from a reputable breeder. I used the same technique I use on corns, but nada. I'll probably just try and find someone local to show me how to do it on a bp.
