Usually no, By using the right absorbency for your menstrual flow, this make insertion easier. For example, you may wish to use higher absorbency tampons when your menstrual flow is heavy and then switch to a lower absorbency tampon on lighter days. If you want to use a lubricant, we suggest applying a very small amount of water-soluble lubricant only on the tampon tip. Too much lubrication will interfere with the absorbency of the tampon. Do not use petroleum jelly or other lotions and creams not intended for vaginal use.
