By 3rd grade... you may well already be too late.
25 years ago, a girl in my 3rd grade class got pregnant, we all knew what sex was, almost none of our parents had clued us in... but older siblings sure had.
Last year, we found out a lot of the local boys (different schools, from local sports teams and drama groups) were experimenting with oral sex, because even though most of them had gotten the birds and bees talk, most people didn't include oral sex in their spiels.
Give her the information. Before homones, it's just protective, not attractive. In fact, except for the taboo nature of it, sex is pretty gross before homones. Sounds like as much fun as sticking your finger up your nose.
