Sterilize the applicator before every use by putting it in boiling water for 3-5 minutes or use Menstrual Cup Sterilizer. Apply the lubricant inside the clean applicator, on the rounded tip and on the rim of the sterilized menstrual cup. Fold the lubricated menstrual cup using C-fold or Punch-down fold. Put the folded cup inside the applicator and push in the stem until the cup touches the rounded tip. Insert the rounded tip of the applicator into your vagina and push the menstrual cup inside. Menstrual cup insertion can sometimes get difficult for menstruators and always for beginners. It is tricky to aim the folded cup inside the vaginal opening. Continuously retouching the cup to insert it completely can make the cup unhygienic too, because of constant exposure to germs on the hands and in the air.
