No hes retarded and pretends to know things. It can become significantly looser after childbirth in extreme cases you can even get surgery to correct it. Most women will tighten up over a peroid of a couple months and many do kegels/pelvic toning to speed it up. Depends on the birth, depends on the woman. But the overwhelming majority are looser afterwards with varying degrees of retightning over varying degrees of time time.
For maximum screaming, time sleeping with her family member to her period, she'll be exceptionally angry as part of the natural way of things!
