There have been videos posted on here, and I am sure you could probably find them if you search on youtube, but have you thought about "popping" your snake?

I have never tried it, for fear of hurting my snake (plus I got my snake from a very reputable breeder, so I have no reason to question the sexing). It does look fairly simple though, and from what I understand it is more reliable than probing?
