Hereditary

I was wandering, Is penis size hereditary?

I look like all the guys on my mums side of the family. When I stayed at my cousins house when we were both 13 we both had similar size dicks, about 5.5''.

My brother looks like the guys on my dads side and the all has a smaller dick, like my cousins on that side.

So is penis size hereditary or is this a couincidense?

It's hereditary like all of your other physical characteristics. You've got genes from both sides of your family, so your not either like one side or another, though you might look more like your mom or dad depending...

No guarantee but yeah I'm pretty sure it's heredity. But don't worry about it, it wont do you any good to be self-conscous. (Probably spelled wrong: English is not my best subject).
