Despite its stigma over the years, lube is (finally) becoming a normal and accepted part of sex. Women who experience vaginal dryness or dyspareunia—pain during intercourse—are more likely to use lubricant more frequently, according to a 2012 study in the Journal of Sexual Medicine, but almost two-thirds of women in general use lube.

A 2014 study published in the same journal found 65.5 percent of women reported using lubricant in their lives, although only 20 percent said they had used it within the past 30 days. The main reasons they used lube: to make sex more comfortable, fun and pleasurable, and to decrease discomfort and pain, according to the study.
