I don't know since I never had a brother.

From my time spent on LPSG.org and reading the comments from those who have brothers I would say its a crap shoot. Sometimes the older brother is bigger, sometimes the younger brother is bigger. Sometimes only the father is bigger or occasionally the sons are bigger then their father.

I guess genetics only take it so far, the rest is just the luck of the draw as it would seem. I have no idea how my son is going to stack up against his father when he is grown. I just hope he ends up at least average so he doesn't have to feel self conscious about himself.

I'll still love him and I'm sure his partners will to; he's got incredibly good looks going for him (seriously I wonder if he is actually mine..LOL ) so I imagine he will have less trouble finding a partner willing to accept him even if he isn't very well equipped!

I wouldn't worry, Fillin. I'm sure that you know that sexual attraction is a lot more about attitude and a person's brain than it is about size. If he's got a personality to go with those good looks, that's what partners and friends will love him for, far more than just that one body part.

My brother's was very different. Longer and thinner

Yeah I agree completely!!

He at a very young age is already a ladies (and men) man; people stop us EVERYWHERE to comment on him. So I take pride in the fact that my son is probably going to have the pick of the litter when he's older (boy or girl). I'd post a picture of him but am very leery of doing so. He really is the cutest boy I have ever seen and I'm not just saying that because he's my son..I'm gonna pimp him out to modeling agencies when hes old enough..just watch..LOL Just kidding!

My biggest fear is when he's a teen and has friends sleeping over. I'll be just as happy if he's straight or gay but their has to be rules about fooling around in the house. Not sure how parents of gay or bi sexual children handle that and even though that is a long ways away..I'm already worrying about it!

Hes my son so of course I'm going to make everything a much bigger deal than it has to be..LOL

I have two older brothers. I am larger than both, and larger than my father was! I know this from sight, and I fucked a woman that my brother fucked! She told me that I was much bigger than my brother!! I asked how much, she said 3" bigger at least. I'm almost nine inches. My other brother and father was that I'm bigger soft than they are.

Do brothers have the same size everything? No, not usually.

Great point Ben!

Hard to expect one small aspect of the anatomy to be the same when their is so much variation with everything else. I mean hell sometimes hair color, complexion, height and facial features make it difficult to correlate siblings.

Probably true but what if they are twins?

wouldn't necessarily correlate... depends on what genes they get passed from the parents

I know my father was very well endowed and I don't remember about my brother. It has been years since I had seen his. I am average but I think he was more on the "gifted" side.

Back in the day I used to get off with brothers- one was 2 months older than me, the other about 3 years younger than us. The oldest and I were about the same length, but the youngest had at least an inch and a half on us. Jealous? Me?

I know iam bigger than my brother.

I'm bigger than my brother, but not my much, less than an inch.

I never saw my Dad's cock hard, but he had HUGE balls that hung down and he was uncut. All, I can remember were his huge balls. Never seen a big pair of hangers like his since,

Just wondering, how did you see your dad's sack but not his meat?
