Why is my penis so much bigger than my brothers? His
penis is real small next to mine.

Penis size differences can vary greatly, even among
direct relatives. Every person's body grows uniquely
just like in the case where one brother may be much
taller than another sibling.
Age is also a factor. If your brother is younger than
you then he may still be developing and have not yet
reached his peak of penis growth.
