When does my peins get larger?

Penis size can change due to various factors, including puberty, which typically occurs between the ages of 9 and 14, when growth spurts happen. Hormonal changes during this time can lead to increases in size. Additionally, factors like weight changes and blood flow can temporarily affect size, but significant permanent changes usually occur during puberty. If you have concerns about growth or development, it's best to consult a healthcare professional.
