[Sparrow]

Hey guys, just registered on the forum!
Nice to meet you all, i've been for some time researching about these kind of techniques but then i found the forum and i had to join it! My problem maybe kinda common, i don't know... i mean, i'm a beginner at this kind of gym lol. But i've been watching porno movies, even amateurs and i feel kinda insecure about my penis size and i thought that i should start a routine with PE! But i mean, around here we use cm and i used a calc to translate to inches and i'm around 4 inches long hard =[
Has any of you guys passed by the same thing and are confident and better "builded" now?
I mean.. i'm asking for some assistance.. at least moral =(

Sorry if my english sucks, i'm from Brazil lol
