This isn't true and all you're doing is being harsh to yourself. Many girls can't orgasm from piv alone and 4 inches is more than enough to stimulate all the spots that matter. Besides the g-spot which is roughly 1 1/2 to 3 1/2 inches deep on average most of the nerves run just inside the inner parts of the vagina. Once you're past that there isn't much to stimulate besides the a-spot and not many girls enjoy having that area stimulated anyways
