If a condom gets stuck inside the vagina, it is important to remove it as soon as possible to avoid irritation or infection. Here are some steps to follow:

1. Stay calm and relaxed. It is important not to panic.
2. Go into the shower or lie down in a comfortable position.
3. Reach into the vagina with one clean finger and feel for the condom. It might be deep in the vagina, but it cannot get lost up there.
4. Once you locate the condom, use one or two fingers to gently remove it. It might be slippery, so it might take some effort to get it out.
5. If you cannot remove the condom completely or you are not sure if it is all out, call your doctor or visit a health clinic right away.
6. Even if you do get the condom out, it is still important to see a doctor or go to a health clinic to be tested for STDs and pregnancy.

It is also important to note that leaving a condom inside the vagina can lead to irritation or infection, so it is crucial to remove it as soon as possible.
