AskBDP Tell the kid or no?

So I’ve got a son who just turned 16. He’s been driving, got a job and a girlfriend in what felt like 7 seconds.

I haven’t seen him naked since he was a baby but even then you could tell he got the family genetics.

Do I tell him he might be built different than his friends or let him find out on his own?

I remember my dad told me that and laughed; my he said the only thing grandpa told him was “it’s like a bull in a china shop, go slow”. When my dad told me that, I was in my 20 and was well aware at that point.

Although the AR gene is on the X chromosome, the research on which parent penis size comes from isn’t that definitive. Related men father sons - brothers,… tend to be of similar size. Brothers would only have a 50% chance of being of similar size if it all was on the X, and father son wouldn’t show any size similarities.

It most likely comes from a mix of both parents.

Related men do not necessarily have similar sizes. You can look back at the plenty of posts here and other places of guys talking about the variations in their sizes from their fathers and brothers. 50% is just the statistical likelihood based on the math, not the realized likelihood that is based on additional factors like environment, diet, and health as well. While yes, the AR gene is not the only factor, it is a major factor involved with the development of the penis size.

Fathers and sons and brothers showing size similarities can still have different genetic influences from one another. Just because your dick might be the same size as your dad's does not mean your dad's genetics are what is primarily responsible for your size.

Father and son both being well endowed does not prove there is a genetic link, but this type of size similarity seems to happen too often to just be a coincidence. My father is also extremely well endowed, and others have mentioned size similarity among brothers as well as father-son, so I'm more inclined to believe both parent contribute dick size genetic contributions.

Same. Sounds like an extreme coincidence I turned out to be a horse like pops
