Hi, I'm 18 Years Old With A Penis Size Of

Hi, I'm 18 years old with a penis size of a carrot and it's really embarrassing, I have facial hair, I have armpit hair, I'm even putting on a lot of muscle. The thing is I have a really small penis, I don't know what to do, I'm a little overweight but not enough to make me have a penis the size of my pinky.
