When I was 13 years old , I remember that I”ve had a 5 inch dick. At 20, and my penis was still 5 inchies long. After I”ve started PE it has grown 0,5 of an inch. The question: Why did it stoped growing at the age of 13? I Remember that , at that age my dick was longer and thicker in copmarison with a friend of mine , wich is older than me with 2 years, and then a cople of years latter his dick was bigger then mine. What do you think it happened? Could it be because at thatage I”ve begun to develop an uppwart curvature?
