Hmm. I think I will take my counsel (and that of an orthopedic surgeon and a radiologist) over yours. It's fortunate that the Internet is around to correct them! Right. But female fetuses do spend nine months developing - and their hymen does not close off their vagina completely. So it looks like only half the population of the planet has their vagina exposed to amniotic fluid WHILE THEIR BODY IS DEVELOPING AND GROWING. Oh, and BTW - I'd suggest you peruse some textbooks on human development. You'll discover that for the first few weeks the embryo is completely exposed to amniotic fluid. Indeed, at about four weeks your entire spine is wide open to the fluid in the growing amniotic sac. And yet amazingly, somehow we all survive that horrible trauma.
