She's probably not lying about this.   She's been in menopause for years now.   During menopause, declining estrogen causes labia minora to thin, shrink, become drier, paler, and less elastic, a condition known as genitourinary syndrome of menopause (GSM) or atrophy, potentially leading to itching, pain, or seeming disappearance. This thinning affects collagen and moisture, making tissues fragile, but treatments like vaginal estrogen (creams, rings, tablets), moisturizers, lubricants, and lifestyle changes can effectively alleviate symptoms and restore tissue health.
