I lost 56 pounds. I will not say that it will make you penis larger, but it will help you in overall health, which will help you sexually. You will be able to see it better when you look down at it, and it may appear bigger once your body fat is reduced.
The biggest change I noticed when I lost weight was the ability to have better sex. My flexibility and stama are much better. I am now able to get more of my penis inside her with a flat stomach.
Shaving the pubic hair away also helps make your penis size look larger.
