1. Open the packet and remove the female condom, taking care not to tear it. Do not open the packet with your teeth.
2. Squeeze the smaller ring at the closed end of the condom and put it into the vagina.
3. Make sure the large ring at the open end of the condom covers the area around the opening of the vagina.
4. Make sure the penis goes in the female condom, not between the condom and the side of the vagina.
5. After sex, remove the female condom immediately by gently pulling it out. You can twist the large ring to prevent semen leaking out.
6. Throw away the condom in the trash, not the toilet.
