Can there be a real treatment for penis enlargement or are all ads phony?

They're all phony. You realized that all along. If you've got 3" or more, you've got enough to get the job done, enjoy and give satisfaction. A smaller penis gets harder and gives you more control over the most sensitive nerve endings on her body, which are near the front. A larger guy is more likely to be incompatible with more women. And really good lovers use their entire bodies & communication skills.
