Don't feel silly. It took me ages to get the hang of it when I first started keeping snakes, they use the same system to denote the sex of snakes.On the subject of moulting you need to know how many moults it had before you bought it and not many places tell you. I do have a few that came as 1st, 2nd or 3rd instars and one which was a 6th instar so I know what they are but most you never get to know how many moults they've had.
