Lotions and oil-based OTC products aren't good lubes, either. "Vaseline is not ideal because it's oil-based and will degrade the integrity of a latex condom," says Jenni Skyler, PhD, LMFT, and CST, an AASECT-certified sex therapist, sexologist, and licenced marriage and family therapist for Adam & Eve, to POPSUGAR. "At the end of the day, all products (from whipped cream to Vaseline to over-the-counter lubes) going into a vagina or anus will essentially expose those mucus membranes to higher absorption of chemicals into the bloodstream," she says.
