I wasn't particularly sexual at that age. I mean, I expected someday I would have sex and believed I would enjoy it (I do), but it wasn't anything like my main concern. I like some chick flicks and I liked shopping when I had fewer responsibilities. Never have been super girly or romantic, though. I'm kind of too pragmatic for either.
“There are two novels that can change a bookish fourteen-year old’s life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs.” ~ John Rogers
Some friends say that things will come in time for her; which is true. But she is feeling stressed now that all her friends had 'grown up' and she hadn't. I suggested she give the whole growing up thing a try - if she doesnt like it she doesnt have to continue.
To most of us this comes rather naturally but i don't know what to suggest for Sarah.
Any way to type her or figure out how to help this poor girl??
So you call her poor because she is stressed out... From your description she seems pretty strongly artistically interested (and mentally in general, perhaps). If she attributes all her energy to the activities you describe, that might be an explanation for the apparent lack of sexual drive.
But what is her or your basic worry (as someone pointed out rightly)? That she wouldn't fit in, wouldn't become happy, or would be unaware? It's great if people find what they want, but certain things you can't force...
