That's not big, the average female pelvic opening can maximally anatomically accommodate an object with a mean diameter of 4.3 inches and a circumferential measurement of 14.2 inches. Depth is meaningless, girth is much more critical to vaginal and anal development. This "big dildo" is approximately 1 inch thick with a circumference of about 4.5 inches. The average female vagina could be trained to take 11 of these dildos simultaneously. Quit underestimating holes. Holes should be tested and developed like a science experiment. And they will.
