I don't think they were that bad, I highly doubt that they're tried to rape Sasuke. Age of consent laws in japanese culture aside, I don't think they had any perverted thoughts of Sasuke at that age they were at. I think they were more lovey dovey thoughts and all that sappy crap. I especially believe that Sakura never had thoughts of losing her virginity to Sasuke (*Shivers* That was really hard for me to type) considering that 12 year olds don't think about that stuff too much (At least I hope not O_O) and that girls aren't as perverted as guys are. (Hey, at least I'm honest about it and willing to admit it dammit

)
Now that Sakura is 16 and has feelings for Naruto, I probably wouldn't be surprised if our favorite pink haired kunoichi had some fantasies of having her first time and losing her virginity to our favorite orange jacket waring shinobi.
Now for an on topic comment, I believe that Sakura has moved on from her crush on Sasuke a long time ago and I'm not crossing out the possibility that Sakura and Naruto knew each other (and possibly were childhood friends) before Sakura even knew who Sasuke was. That's my story and I'm sticking with it.

I pretty much agree with this, Ino was the more aggressive fangirl with Sasuke- glomps him at least twice that we see, much to his disgust. Ino was more hardcore than Sakura, Sakura was pretty much all lovey-dovey words and looks, and she realized it was one sided before too long. She kept trying, yeah, but there was pretty much always a vibe from about chapter 4 onward that she knew it was one-sided and would likely not change. Ino never picked up on Sasuke's disgust at her antics. Ino seemed to have the standard peer group opinion of Naruto and we don't see her opinion really shift about him, even when he wins his battles in the Chunin exams (battles she witnesses) where with Sakura, although she carries the standard opinion on the surface, even as early as chapter 5 we see empathy, admiration and attraction- from the first time we see her witness Naruto doing battle on panel.
Even in the manga flashback where Sakura shows sorrow over Naruto's pre Academy childhood, there's perhaps a subtle hint that just maybe she had known him then and hadn't understood why the adults all hated him.... So I think there some merit in your theory.
