However, medical practitioners worry that two condoms may wear against one another during sex and one or both will tear during intercourse. One study suggests tearing will occur one in five times during double bagging, compared to one in 50 times for regular condom use. For this reason, people are cautioned against double bagging, as well as using a male and female condom at the same time.
If you’re motivated to double bag to provide further protection against pregnancy, you may like to use a condom with another hormonal contraceptive method, like the Pill or the Patch. Spermicides can also make condom use more effective.
If a fear of breakage motivates your desire to double bag, you may like to use a personal lubricant. Personal lubricants can reduce friction against the condom which in turn makes tears less likely. Water-soluble or silicon lubricants should be used with condoms as they do not corrode the latex or latex-like material like oil-based lubricants can.
