Hello,
First of all you should learn to be pleased with your penis size. The average penis size in 4-6 inches, so at 7 inches you are above average.
Regarding pills working. The answer is an affirmative NO. They’re simply worthless herbs and while they won’t hurt you, you’re essentially flushing your money down the john. The sellers of penis enlargement pills are counting on the placebo effect to work. You’ll take the pills and in your mind your penis will seem bigger, but your penis will be the same size as when you started.
There are only two forms of penis enlargement clinically proven to work.
A) Surgery. Surgery is expensive and anytime you put yourself under the knife you are putting yourself at risk.
B) Exercises. These are manual exercises you can perform a few minutes every day that include jelqing, pumping, rotoring and many others. You can add around an inch or two in length and a little over a half inch in girth.
It should be noted that women prefer girth to length for the simple fact that it provides more friction during sex. Most exercise programs focus on length only. This program I recommend you check out covers both. http://www.superlargepenis.com
I wish you the best of luck.
