Yungun, what your teacher said is somewhat true and sometimes completely false…. hehe well you get the picture? maybe? no?
Well, according to all manner of surveys and statistics, the size of one’s penis should correllate slightly to one’s height.
Although it’s just a slight increase in the average length according to your height…… or at least thats the theory…
so say you have two people, one of them is one foot taller than the other. theoretically, they should each have a proportionately length’d tool…. eg a 5” and a 6” say….
unfortunately (especially for us tallish people) this is not always the case….
it sucks when a real tall guy gets shortchanged.
and this happens.
Also especially since most people (eg GIRLS) EXPECT that the taller the guy, the bigger the dick…. :(
EG: I have noticed by personal observation that alot of pornstars are really just shortish guys with longish penises - that that they look doubly large….
I dont think you mentioned your age, but if your brother is 17 then you must be (i am assuming) fairly young too…and you probably havent finished puberty yet either, so you should take advantage of your best growing years and pack on some serious gains!
