If the males have an average length, do females have an average depth?

My thing (6.7 inches) disappears almost all the way inside my wife who is a pretty tiny woman. Makes me wonder if the average female is even deeper

Edits: 1. TIL that vaginas don't have a set depth but they stretch to accommodate the item being inserted

1. TIL that I've been reading an inch tape measure wrong my whole life. It's 6 ¾ not 6.7 inches
