Doctor's answer:

Exercise
During daily life, you can do some squatting exercises or kegel exercises, or you can also choose some aerobic exercises. This type of exercise promotes blood circulation in the human body, ensuring that the penis has sufficient blood supply during sexual activity. Over time, this can gradually expand the penis, making it larger.
Dietary Methods
In daily life, you can consume foods that enhance male libido, as these foods are generally rich in male hormones. This can make male characteristics more pronounced. The penis is considered one of the most prominent male features, so eating more foods that boost libido can help make your penis larger.
