Is withdrawal more effective or condoms more effective?

Patient's question:

No

Doctor's answer:

It should be noted that the best time to use a condom is after the penis is erect, but before it comes into contact with the vagina. Do not use expired condoms, as expired condoms are likely to break during intercourse. After ejaculation, even if you are still erect, immediately withdraw the penis from the vagina. While withdrawing the penis, hold the base of the condom to prevent it from falling off.
