ive noticed my male and my cousins male have thick tail bases, larger spurs, and a slight lump right below the vent that my female does not have. my females spurs are sooo small you can hardly see them and she has a skinny tail compared to the two males.ofcourse this is only from 3 snakes so i dont have a vast amount of resources to be more accurate.

although i wouldnt use it as 100% law it does seem to hold atleast some truth, IMO. you still cant be 100% sure without popping or probing.
