And by no purpose I mean in your sexytimes, not in everyday life.
That isn't a curable thing; it's hereditary. It's in your genes and is a part of you, wether you like it or not. Trying to change a part of yourself will only make you miserable and insecure. I highly advise you to be grateful that you were even given a definite gender; I have a friend who is a hermaphrodite, she (only the female part functions as it would normally) would give anything she has to not have to suffer the indignity of an 'editing surgery' to make her a definite girl. Take pride in every part of yourself and it won't matter to the 'one' for you that little you isnt as pronounced as the next guy's, they will love you for who you are and won't be obsessed with something that will serve absolutely no purpose once you pass 55 or so.
First it seems love a challenge, has not lived his life to the full yet.
If you are intrested in jelqing just go to pegym and read up about it, there you can also find a begginners page and take from there, dont try to rush it and do as they say.
Good Luck
are you sure its a problem small because all different sizes are for different women less concentrating on the size and more of enjoying pleasure time with a partner
You can't cure that and jelqing causes damage to the penis. Accept your penis for what it is.
