Itching down there can be caused by a variety of reasons including infections, irritation, allergies, skin conditions, and hormonal changes. Common causes are yeast infections, bacterial vaginosis, sexually transmitted infections (STIs), and contact dermatitis from irritants like soaps, detergents, or feminine hygiene products. Itching can also result from poor hygiene, sweat, stress-related hormonal changes, or skin diseases such as eczema or psoriasis. Sometimes, shaving or improper care can lead to irritation and itching as well.
If the itching is persistent, accompanied by unusual discharge, pain, or sores, it is advisable to seek medical advice for proper diagnosis and treatment.
