Patient's question:

Started masturbating since high school, male, 28 years old now, feeling penis is small (not sure if it counts as small), still get erections every day, not sure if the hardness is up to standard, and don't know what long-term masturbation has caused now

Doctor's answer:

Premature ejaculation is generally when sexual activity lasts less than 2 minutes. This condition can usually be cured. If you have kidney deficiency, it is recommended to take Liuwei Dihuang Wan combined with Jinluo Gujing Wan for treatment, which has a very good effect. If you have excessive foreskin, it is best to have surgery to remove it. You must also avoid certain foods and drinks, and do not have too frequent sexual activity.
