How can family members have different penis sizes?

Ed C: How can family members have different penis sizes?
I have three brothers and we all seem to have different penis sizes even though we all look pretty much alike. How does this happen? Shouldn’t we all be around the same, or the same as our dad? Does anyone else find they have different sizes in their family?
It is not incest! If you have brothers all around ur age, you can’t avoid seeing each other naked time to time. And of course you see naked at the gym or pool change room.

poeple seriously give immature answers….but no its not a common thing to have the same penis sizes….every member in your family has a dif dick size it will either be bigger/smaller/or rarely the same size as you…. do to all the dna that comes from the parents/grandpartents..ect that will determine your cock size

Answer by Lilly
penis size is genetic but you can inherit this gene from any male in your heritage. could be your grandfathers gene, could be your mothers great grandfathers gene. you dont have just mostly your dads and moms genes. family genes stay in their offspring and can be dormant(not in use) but can again become active in a new child. so no, it is very normal that you have differences.
