The penis reaches adult size over a number of years during puberty (the years during adolescence when boys and girls grow and change to become adult men and women). A boy who matures more slowly than his friends will not get an adult-size penis until late in adolescence – and this may cause anxiety or make him feel as though he has an abnormally small penis.
Herbal remedies, Kegels (pelvic floor exercises — learn more here), and exercises have all been mentioned as potential ways to make your penis bigger. However, we’ve searched and searched for medical evidence that these techniques will work to grow your penis, but there’s simply zero, zilch, nada, no evidence. You may find lots of unverified anecdotes, which come from a sample size of one, but they simply cannot be trusted. After all, no one on the internet knows you’re a dog (or liar). We recommend that you avoid these techniques.
