Answer Maybe they are bigger 'cause they are adults. Or people grow differently, sooner or later you'll have big breast.
There is no reason for you to want bigger breasts
Not sure this is what I want to know
well..... my cousin has bigger boobs than her mom so its possible she is a d4.
Honey, they'll get bigger in time trust me!
Big breasts, growing waist size, bigger buttox.
No they don't. some girls are just petite. I'm 14, only size 34a. i have a friend that is like 36aa or something. so yeah. and some girls don't grow boobs at all. if you're concerned, go see a doctor though. answer: Yes, all mammals (male and female) have breasts. Some are bigger than others. Girls mature at different rates, so it may take a while for some to develop breasts.
some girls do some girls don't.
Think of it this way. Given the choice, would you choose a girl with smaller breasts or a girl with bigger breasts? You would pick the woman with the bigger breasts, wouldn't you? It's the same for women.
I personally think that it is up to how the girls breasts are growing at their age, everyones breasts grow at different ages! I am 11 years old and Im wearing bras. But still girls that are my age have bigger breasts than me. hopethat helped :)
If you are a boy, look at yours, now imagine that about 10 times bigger.
Because it's a part of growing up. Also it has to do with puberty. To make it simple girls are developing or becoming women.
The make you breasts look bigger but they do not make your breasts grow bigger.
