Doctor's answer:

Exercise
During daily life, you can do some squatting exercises or kegel exercises. Alternatively, you can choose aerobic exercises, as such exercises promote blood circulation in the human body. This ensures that the penis receives sufficient blood supply during sexual activity, gradually expanding it and making it larger over time.
Dietary Methods
In daily life, you can consume foods that enhance male libido, as these foods are typically 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.
