we are talking about a piece of flesh either being able to stretch to accommodate, or alternatively unable to stretch to accommodate (and hence tearing). I don't see how psychology enters into it. That would be like saying that women get stretch marks on their belly because psychologically they are reluctant to allow their skin to stretch to accommodate the baby bump. Some women have more collagen and their skin is more pliable (lucky ducks!) whereas others are bound to stretch and tear. Of course having a forceps delivery will virtually guarantee tearing, but I don't think that's what Melody is talking about. BTW Melody you lucky duck not tearing at all with such a big bub!!
