It's much easier for a girl to opt out of societal expectations (in a modern society, that is). For someone like me who is not at all ok with expectations of any sort, being a girl suits me very well. I don't have to do anything I don't want to do.
That is a really interesting observation, and I think you're right. That idea actually makes me kinda happy.
I would like to add, that women aren't usually under much pressure as far as the size of their sex organs are concerned. It's not at all like a man, where size and skills can make or break a romantic encounter. Women don't typically have to worry about being "adequate" in that regard.
A thought has just occurred to me: some women seem to care about breast size. Is that common or am I seeing isolated cases?
I'd say most women care about their breast size. I think it started as evolutionary biology: The more feminine a woman's characteristics, the better genetic specimen she is perceived to be by the opposite sex, facilitating propagation of the species. (Not that it really needs any help these days, lol.) From there, society grabbed hold of this concept and really blew it out of proportion.
FWIW, women who have had breast implants generally report a huge increase in self-confidence.
In addition, I think one of the huge advantages to being a woman is, simply, possessing the grace and beauty of a woman. Even average-looking women still have the smooth skin, the aesthetically superior shape, and the grace that very few heterosexual men possess. And that is a powerful thing.
If you're one of those lucky girls, sure. But really, smooth skin and an aesthetically pleasing shape are superficial things. It's what's inside that counts, right?
Even if you are never a mother, women are revered as having those motherly qualities.
I wish I had those qualities, but I don't. I'm very much a tomboy, and my emotional IQ is quite low. I just learned this, so I'm at the beginning of a long journey to change it.
