4 You use the wrong lubricant
Oils or oil-based lubricants (including Vaseline, baby oil, and mineral oil-based body lotions) can dramatically weaken latex condoms in just 60 seconds.
Choose a water- or silicone-based lubricant, available in the family-planning aisle in drugstores and supermarkets. Also keep in mind that many lipsticks contain oils that can weaken latex.
