Short answer: yes and no.
A slightly longer answer: It's the lack of preparation and thusly forming micro-scarring that does it. Scar tissue (especially with how hyperactive it is on humans, but I digress) doesn't stretch, not does it take well to lubrication. Vagina is (simplifiedly) a muscle, it doesn't just turn "loose" when stretched, like a frozen rubber band. You wouldn't tell a split performing gymnast, that her leg muscles are now too loose for walking, now would you? A limber and strong snatch is more fun than one that isn't, that's for sure.
