I have no idea about the sex as I never asked (it doesn't matter to me. It's my first and as thus is a gateway to potentially seeking more snakes) I was just really set on having one. So why do I need to know the sex? It's not going to change how I handle it. Think of it like a car. It's neither male nor female, but you love to touch it when you're near it, and you see it daily. It makes you happy. Thats what I plan on twist doing for me as well.. till he's 5ft and constricts my arm.
