Does alcohol consumption lead to erectile dysfunction during sexual activity?

Patient's question:

Today I had a little bit of alcohol, but for some reason, when I tried to have sex at night, my genital was not hard. I'm very worried. I'd like to consult here: does drinking beer lead to premature ejaculation in sexual life? Friends who know, please help me solve this, thank you

Doctor's answer:

Drinking beer can lead to premature ejaculation, which is caused by alcohol stimulating the corpora cavernosa of the penis or enhancing blood circulation in the penis. Excessive blood flow can result in the inability to achieve normal and complete sexual intercourse after an erection. In such cases, it is important to avoid drinking beer before or during casual or regular sexual activity, especially when the body is not in good condition or when working overtime. This generally reduces the quality of sexual life.
