Condoms help to stop the spread of disease when they are used every time, the right way.
Use a new condom each time you have vaginal, anal or oral sex. Check the date on the package to make sure it's not too old, and open it carefully. If you do not pinch the tip, the condom could break. Put the condom on the penis after it becomes erect but before it enters the body. If you are uncircumcised, pull the foreskin back before putting on the condom.
