If you’re experiencing vaginal dryness after treatment, using a lubricant may make sex more comfortable. Oil-based lubricants can increase your risk of getting a yeast infection, so it’s a good idea to select a water-based gel. You may also consider using a vaginal moisturizer which is not the same as a vaginal lubricant. Unlike a vaginal lubricant which is used right before penetration, vaginal moisturizers can be applied several times a week to keep the vagina moisturized.
