First hello andto our forum, now as far as sexing spurs are found on both males and females and cannot be used to determine the sex of animal.
Best way to determine the sex is by popping or probing (finding someone to show you how to do it would be best)
Now as far as your snake can you please post a picture, given the description it may or may not be a Ball Python (see highlighted part of your thread) and before making assumption I would rather see the animal.
Here is how to post pictures http://ball-pythons.net/forums/showt...l=1#post326201
***Edit If the snake in you gallery is your snake it is indeed a BP (not green and black though) they reach 3 to 5 feet, females being larger than males.
