I say, and with God's success: The placement of the cotton is recommended for a virgin during menstruation, and for a previously married woman in all situations. Its position is at the site of virginity, and it is disliked in the inner part of the private area. Refer to: Sharh Al-Wiqayah p. 121, Umdah Al-Rayah 1: 122, Dhakhr Al-Mutahilin p. 62, and others. And God knows best.
