I've never had that happen and I've had some big babies vaginally. And, my lady bits don't seem to have gotten bigger - seriously. When we're intimate again after a baby is born, it's more like it was the first time we were ever intimate (very tight - uncomfortably so). I think it can be different for different people, but I honestly have not found that to be true for me. I think I'm part ninja, though, because that area seems pretty strong - maybe it's the kegals.
