Hi bennett - I ‘ve rarely read so much bs in that concentrated form.
I would assume that dick size is 50+% hereditary the rest up to 100% never developed in most men, rather a potential - gains through pe, that - in my opinion - would be the major env. Factor.
Genetics is a bit more complicated than what you seem to believe. You and your brother are not a copy of your dad, not regarding your dicks, not regarding the rest of you. Rather, you are combinations of the genes of both your parents which results in all possible dick size within the offspring of a couple.
Modify what you’ve got through pe and forget about other env. Factors.
So if I were to have a son with a girl who’s father is well hung, there would be a good chance the kid wouldn’t have a small pecker like myself? I don’t really want to have kids if they will be cursed with my same endowment.
