Control. With the female condom you have control over the transmission of std's even if your partner does not want to use a condom.
Female Condoms. 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. Can be found at your local reproductive health clinic.
