I agree with the general sentiment about the girl's (possible) subconscious, or even conscious, explanations for her clamped vagina.
However, the statement, "Hey, a baby can fit, why not my penis?" neglects the fact that a baby doesn't just pop out of a normal ol' vagina. The symphysis pubis (cartilage separating two parts of the pelvis, directly in front of the vagina) expands a great deal thanks to pregnancy hormones, in order to fit the baby's head through there. If this physiological change did not take place, there is no way that a baby's head would fit. Now, I know that is more of a structural thing than a tissue thing, but still... babies don't just fly out of vaginas without a lot of stuff happening first.
Just wanted to add that semi-non-relevant fact to the discussion.
