In her 10 years at the Center for Sexual Health Promotion at Indiana University, codirector Debby Herbenick, Ph.D., M.P.H., has studied intercourse from every angle. Most recently she asked how couples use lubricant in the sack. The study is ongoing, but here’s what Herbenick has found so far: Nearly half of women find it easier to reach orgasm with lube. That’s reason enough, she says, to keep a water-based formula, like Good Clean Love in your nightstand.

A UCLA study study found that 36% of women who eased friction with a slick product like massage or baby oil developed yeast infections, compared with just 4% who didn’t. And using petroleum jelly more than doubled the risk of bacterial infection, from 18% to 40%. The researchers suggest using a lubricant that mimics natural fluids, like Good Clean Love or Pre-Seed.
