What are the correct methods and precautions for using condoms?

Patient's question:

No

Doctor's answer:

Wearing a condom is very important throughout the process. After the penis becomes erect, gently squeeze the reservoir tip at the top of the condom to expel the air inside, then place it over the head of the penis. Use the palms of your index, middle, and thumb fingers to roll down the unrolled part towards the base of the penis.
