Erectile dysfunction? What to do about sexual intercourse difficulties?

Patient's question:

Failed in all 4 sexual encounters with his girlfriend, unable to achieve an erection firm enough to insert into the vagina, had never had sexual intercourse before

Doctor's answer:

First-time sexual experience due to lack of experience or psychological tension, many people have experienced weak erection.
Encountering this situation, don't worry first. Pay attention to daily living habits, exercise appropriately, and wait and see for one month.
