Is a virgin girl's examination of dryness using a tissue at the end of menstruation to ensure purity sufficient and correct, while avoiding insertion out of concern for her?

Purity after menstruation is known by the term ihtisha’ (checking with a piece of cotton). If it comes out clean, without any trace of blood, yellowness, or turbidity, then purity has been attained. A virgin looks at the outer part of her vulva when sitting, and it is obligatory to teach her the rulings of purity. The Hanafis are of the view that it is recommended for a virgin to insert cotton to verify purity, and its place should be where the hymen is located.
