Before putting on your condom, you are advised to do a thorough visual check that the condom has no holes, tears or imperfections or any other unusual ridges etc.,
If time permits and you have patience, you can do a water test by pouring water inside the condom and hold it from the top to see if there is any water leakage. Even if there is a minor water leak, you need to discard that and use a fresh one.
When you do the water test, the lubricant that is present in the condom could get washed away, so you may need to use additional lubrication to perform better.
