Im 19 years old, and my penis is only about 4 inches long when hard. I am also quite heavy, about 295 pounds and about six foot tall. I have decided to lose the weight, and aside from other obvious health reasons, one of my other reasons is i heard that the more weight you lose the bigger your penis becomes. Now im not asking hey if i lose weight, will m penis gain inches? MY question is, can fat hide some fo your penis' length underneath?
