What are the causes of premature ejaculation?

Patient's question:

Is intercourse lasting less than 3 minutes considered premature ejaculation? Is an 11cm erection considered small? 3~4cm in a flaccid state

Doctor's answer:

Now there is bacterial vaginosis, and timely treatment is required. During the treatment period, sexual activity should be avoided. Manual stimulation may cause damage to the vaginal wall and cervix, which can exacerbate vaginal inflammation. Therefore, manual stimulation should also be avoided, and attention should be paid to maintaining good hygiene of the external genitalia. Wear pure cotton underwear and change clothes frequently. Patients with bacterial vaginosis can, while understanding the principle of symptomatic treatment, use dietary therapy as a supplementary treatment in daily life. In daily dietary habits, it is essential to avoid excessive hunger or fullness and never overeat.
