I've been dabbling in the field of bettering sexual performance for now 15 years and I've had my fair share of learning curves.
Specifically increasing penis size, I took my erect length from 16cm to 19.75cm and my erect girth from 14cm to 16.5cm in circumference.
Nothing crazy, but results that have made me (and others), very happy.
Don't worry - it didn't take me 15 years to get those size gains, that actually took 3 years.
It could have been WAY LESS if I knew what I know now.
The initial 12 years felt like a yo-yo. I'd get sucked into an ad or flashy product to get nowhere then throw in the towel for a month or more.
But, I really wanted those promised results so I tried the next thing repeating the same thing over and over. Sound familiar?
