You have been given some sage advice in the original thread. I believe it is your insecurity or fragile male ego that is preventing you from accepting and valuing the information in those replies.
Size is not important; what is is what you do with what Mother Nature has endowed you with. I recommend rereading the information in those replies and taking the information to heart.
Whether you are of Asian descent or some indigenous group from Mongoloid stock such as American Indian, Latino, Australian Aborigine, etc., or, simply that your gene pool determined that you would have a short penis is of little consequence in the overall scheme of things. You cannot successfully make one larger and when you consider that much of the world's male population have penises in this range, you are quite normal, and those populations continue to flourish.
I am sorry that the information you have been given is not what you want to hear; however, the truth is, and regardless of size, what matters is how you use your penis and that is universal. Here is the reverse logic:
Say you magically had a penis of some length you decide is adequate, moreover, say you meet lots of guys with the same and much longer members, I'll bet if you enter into a discussion with the group on this topic the majority would all complain that they are not large enough; a minority would agree with Brandye, our resident M.D. and me. To repeat, I recommend putting your time and effort into learning how to be a great lover in and out of bed. Begin your education by reading the many articles listed in
the Index as well as the book: "The Joy of Sex".
