How to treat premature ejaculation?

Patient's question:

Every time during sex, I finish very quickly. It's over in just one or two minutes. Is there a good treatment for this?
First follow-up question: Are there any Chinese herbal remedies that can treat this? I was like this from the very first time I had sex, and later my girlfriend broke up with me (thinking I had a problem). Now my second girlfriend is saying the same thing. I've never felt any physical discomfort!
Second follow-up question: I can't control myself at all; I finish almost right away? Is there any way to solve this?

Doctor's answer:

Hello, methods for men to prolong ejaculation time
　　Whenever urinating, take a deep breath and draw it into the dantian, then close your breath. Imagine this energy flowing from the dantian to the mingguan, along the du meridian, up to the baihui point, and hold this point. Visualize a green "water" character at the baihui point, then begin urinating. After finishing urinating, exhale the breath slowly, while imagining the "water" character at the baihui point, allowing it to descend to the dantian with the breath. This practice is very effective in sealing the essence; even during sexual activity, normal sperm will not be released. Otherwise, you need to open the jingmen. When opening, eliminate all distracting thoughts, and exhale while urinating.
　　
Stand with your feet shoulder-width apart. Place the prepared sandbag and gauze band on a bed or stool, and tie a loose knot in the gauze band for later use. Then, use one hand to lift the penis and scrotum together, and place the loose knot of the gauze band around the base of the scrotum and penis, tightening it appropriately. Leave the pubic hair outside, ensuring the two gauze bands below the knot are of equal length. Finally, slowly lower the sandbag to about 2 inches (5 cm) above the ground and swing it back and forth 50 times. Breathe naturally. The practice is considered effective if the penis and testicles become congested, slightly sore, and there is a mild pulling sensation in the inguinal region without pain.
