Agreed on the snow I.D and that age and morph is perfect to try your hand at candle sexing if you want. Candling is nice, because it's fairly accurate, easy to do and non invasive, so you don't need experience to try it. It's only usable on young snakes and ones with limited pigment though.
Take a bright LED light and the snake into a dim room, place the light against the side of the snake's tail, just past the vent, you may need to move the light around to get the right angle. What you are looking for is one to two thin red lines in a male, that will be the blood in the hemipenes or a clear area on a female. With females, you might also see one or two tiny red dots, that will be the blood in the scent glands.
