bearded lizards

Question
can you tell me every way you know how to tell the difference between a male and female lizard (gecko).

Answer
 An experienced person can tell the sex of a gecko at about 3-4 months old, and it gets easier as the animal gets older.  Primarily, if you look at the vent of the animal then just below, a male will have more pronounced femoral pores, in a slightly v-shaped line, an below that, on the base of the tail, a bulge just as the tail comes from the body.  A female will have a row of pores but they will be so small you'd barely see them and no bulge on the tail base.
