Put the condom on when the penis is erect. Prevent contact before the condom is put on.
Tear open the foil and carefully remove the condom. Sharp object like nails, teeth, jewellery and zippers could damage the condom.
To prevent air is trapped; squeeze the top of the condom between thumb and forefinger. Be sure the roll is on the outside.
Still squeezing the top, place the condom on top of the penis and unroll it over the full length using the other hand. If the condom is not properly applied, avoid any risk and use a new one.
After ejaculation withdraw when the penis is still erect. Prevent slipping by holding the condom in place at the rim.
