Can i use both male and female condoms together?

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. They'll slip/break.
