The erection length seems to be abnormal?

It is normal for boys going through puberty to have varying sizes of erections.
A 10 cm erection is within the normal range, while a 4 cm erection may be on the smaller side but can still be considered normal for some individuals.
It's important to remember that size can vary greatly among individuals.

If your younger child is experiencing pain in the glans after masturbation, it could be due to several reasons, such as friction, lack of lubrication, or even an underlying issue.
It would be advisable to consult a healthcare professional for a thorough evaluation and guidance.

Understanding the normal range of erection size in adolescents can be a source of concern for many parents and teenagers alike. It's important to remember that puberty is a time of significant physical and hormonal changes, and these changes can vary widely among individuals.
In general, the onset of puberty in boys typically occurs between the ages of 9 and 14, with most boys experiencing noticeable changes by the age of 12. During this time, the body undergoes various transformations, including the development of secondary sexual characteristics such as increased testicular size, pubic hair growth, and changes in the penis, including size and function.
Regarding the specific sizes mentioned in your question, a fully erect penis size of 10 centimeters (approximately 4 inches) is within the normal range for adolescents. Studies suggest that the average erect penis size for adult males is around 12 to 16 centimeters (approximately 4.7 to 6.3 inches), but during puberty, sizes can vary significantly. A penis size of 4 centimeters (approximately 1.6 inches) when erect may be considered on the smaller side, but it is essential to understand that individual development can differ greatly.
If your younger child is experiencing pain after ejaculation, this could be a sign of several potential issues. Pain in the area of the glans (the head of the penis) can sometimes be attributed to a condition known as "phimosis," where the foreskin cannot be easily retracted. This condition can lead to discomfort during erections or sexual activity. It is advisable to consult a healthcare professional, such as a pediatrician or a urologist, who can assess the situation and provide appropriate guidance.

It's also important to foster an open dialogue about sexual health and development with your children. Many adolescents feel embarrassed discussing these topics, but education and reassurance can help alleviate anxiety. Encourage them to ask questions and express any concerns they may have about their bodies and changes they are experiencing.
In summary, while there is a range of what is considered normal for erection size during adolescence, it is crucial to focus on individual development and comfort. If there are concerns about size or pain, seeking medical advice is the best course of action. Regular check-ups with a healthcare provider can help monitor growth and development, ensuring that any potential issues are addressed early on.
