Is Getting Precum Genetic?

Dont worry, most guys that precum only precum a little, its very rare that a guy can have precum running down his erection... It's not genetics, its just how you're body is, this is the same with penis length, just because your dad or brother has a big penis dosnt mean you will, also, you have probably only seen your brother's penis when it is flaccid. Just because it is bigger when its soft dosnt mean it will be bigger when it is erect, some males have a big flaccid penis that dosnt grow very much when its erect, it only gets harder.
