First of all, if a man wants to compare his penis size to penis size studies, he has to use the bone pressed measurement. The non bone pressed measurement can’t be used to compared several penises. This issue is related to the variable fat for each male. Let’s imagine the following scenario. You have a bigger penis than someone else but you are overweight and he is healthy. If the non bone pressed measurement is used, you may appear to have a smaller penis than him in numbers. This issue is due to the fat between the pubic bone and the skin. As you get weight, fat is stored in the fat pad. This location is called the fat pad length.
