What determines the penis size you are born with?

**ThomasJohnThomas** · 03-11-2012

What determines your height, your hair colour, your skin colour, the size of any other boddy parts? It is genetics, man! Maby your son got it from his mothers side of the family, or from another branch than you at least.

I've only seen my fathers penis flaccid, and he's definetly bigger than me flaccid. As I recall (I don't want to stare, lol), his flaccid is probably also bigger than my erect penis, and I'm slightly above 6nbpx5 fully erect. My father probably has one of the biggest flaccid penises I've seen so far. And he knows he's got a big one, because one time a couple of years back I asked him this (he's a doctor):

"Dad, do you think starting to work out hard at a young age can lead to not growing as big a penis as if you didn't work out?" I asked this because I started working out pretty hard at a young age (13 or 14).

My father responded something like this "Maybe in extreme cases. Why do you ask? Do you have a small penis?"

And I said "No". (I felt like I was lying, because I did feel a little bad about my small flaccid and me being such a grower)

He said "Well, you've got some good genetics in that department. Really good, actually."

One of the guys I went to school with had a big flaccid. But his dad had a small flaccid. (I've SEEN both).

So there you go. I know it's not much.

My father had an average flaccid and my brother has an average flaccid; however, my flaccid is at most 75% the size of theirs.

It's definitely genetic but like all genetics there's probably not that strong of a correlation between a big dad and big sons. It would depend on the moms genetics too. I mean looks are genetic but the majority of people I know don't really look that much like their parents. Genetics are a very complicated subject.

I wish Sherlock holmes or more preferably Miss Marple would do a "who dun it" so we could finally discover which side of the family dick size comes from.

I'm sure its a complicated mix of genetics and environment.

As to the father's side comment. It makes some sense to me. Both my father and grandfather have absolutely massive flaccids. I don't think my current flaccid(thanks of PE) of 6.5x4.5 is as large, at least in girth.

We are in need of some good research studies involving male members of families.

You get 50% of your genetics from your mother too though. Just because she doesn't have a penis doesn't mean she doesn't have genetics that effect YOUR penis.

If Rasoutin's descendants could be tracked down, we could check with them. If you Google "rasputins penis" you should come up with an alleged picture of the legendary lover's 12 inch preserved dick residing in the Russian Musium of sex.

MY dad has a large flaccid 6"nbp length x 6" girth Minimum

my flaccid is only 4.5 x 5.

But if I have not gotten off in a while or if it's hot outside, it will get to 6 x 5.5 .
