What is the risk factors and danger for using both male and female condoms at the same moment?

Not sure: There are no risk factors that I am aware of, but i must also say that I am not aware of any added benefit to using both male and female condoms together (e.g. Less chance of pregnancy or sexually transmitted infection). Hope this helps.

Slippage, Breakage: Are the only woman-controlled, non-hormonal barrier contraceptive that not only prevents pregnancy but also STDs. Failure rate of 5% w/ perfect use, up to 20% w/ typical use. Newer versions easier to use; men like them b/c they allow more freedom and friction. Careful when removing to avoid spill. Make sure the penis doesn't miss the condom. Never use two condoms together.
