The most appropriate answer I can give you is that there are very real and working ways to get a bigger penis, but not every method is actually going to live up to its promises.
If you're really ready to get a bigger penis permanently, you have to have a good understanding of how the penis works and how you can leverage your natural anatomy and physiology into "growing" the penis for you.
This all might sound a little weird, but spend a couple minutes reading through...
You won't be disappointed.
First up, you need to know how the penis works and what naturally determines your maximum "size".
The penis contains 3 chambers, all made up of a blood holding tissue.
During sexual arousal these tissues fill with blood, thus filling the penis chambers and causing you to become erect.
These chambers are so important because once they are filled, that's it.
You're done.
You cannot be any bigger without enlarging these chambers.
However, if you can enlarge the size of these chambers, your penis will be able to hold more blood and you will have an overall bigger penis.
So many methods fail because they fail to even take into account chamber size, in fact many just trick you into thinking you're growing so that you'll buy another month's worth of whatever the product is before realizing it's a sham.
A prime example of this is penis enlargement pills.
These pills do nothing but increase blood flow to the penis.
Because your penis tissues aren't actually any bigger and can't hold any more blood than before, the blood is wasted and all that you get in terms of "results" is a slightly fuller feeling erection.
Unfortunately, the hardness is sometimes enough to trick men into buying another month of pills, because they think they are starting to grow.
How About Something That Works...
? In my experience, the only thing that actually brought me real penis enlargement was doing penis "exercises".
These are not traditional exercises obviously (no, you aren't going to be lifting any weights with your penis), but they use the same principles of tissue growth.
When you workout at the gym, you put a strain on your muscle tissues that your body reacts to.
In response to the new stress, cell productions in the area is increased in an attempt to better prepare you for the next time you need that muscle.
The penis' tissues can respond in a very similar way, but you'll simply be using your hands to gently move blood through your penis in targeted motions.
These "exercises" will slowly cause growth in the chamber tissues.
While I'm not promising you some "quick-fix", I am giving you something that WORKS.
Besides, many professional exercise guides exist to guide you through targeted daily routines so that you can achieve gains as fast as possible.
