18 and a small penis and testicles ...

Im 20 and mine has barley grown at all since i was 3. My mom said i has not even grown a half inch. i only weight like 125lbs and im 5'6 my weiner is barley an inch and a half erect and not even half an inch long soft. and its only about as big around as a freakin dime. Usually it just looks like a little button above my balls. And it doesnt even barley look like my nuts droped you can barley even tell they are there cuz there so small and my scrotum is still tight like a babys. doctors kept telling me that it would grow when i went through pubert y. but now im 20 and they said that its just allways going to be like that if its only changed as much as it has so far and there not really anything i can do about it. As for yours growing into your 20s you might as well forget that cuz your penis usually stops growing before puberty is over. the doc told me that i just have a really small penis and thers nothing i can really about it. at least yours isnt as little as mine is.

Boys/men who are overweight, must live with a penis which is smaller than a thin boy has. After I went from 60 kg,(132 lb) up to 90 kg,(198 lb) have my penis became 2 cm smaller. But I have 9 cm flaccid and 13,5 cm erect, and it is enough. 1,5 inch erect is very small, the reason must be more than being overweight. There are men who have between 25 - 35 cm (9,5 -13,8 inches) penis, and I know that it is a problem for most of them. Vagina is ca 15 cm(6 inches) deep, but vagina takes 20 cm,(8 inches) easily. If penis is longer, will it, under intercourse, press fast and hard against the bottom of vagina or uterus. And women says that it is very painful.
If a man have 5-6 cm,(2-2,5 inches) erect, so is it possible having intercourse and become father.
