She really should stop worrying about it! Instead she should visualize how she desires her vagina to be. She needs to use visualization and affirmations. She also has to realize that the vagina stretches due to pregnancy and her vagina is staying loose due to possible future pregnancies. This is how her vagina is thinking. It is looking toward the future. So why would it tighten up when it's used to large babies passing through it? Her mind wants the vagina to tighten up but the vaginal mind wants it to stay loose.
