Not sure this applies, but what the heck.
When I was in grade school, I always wanted to kiss Judy - my prettiest classmate. Never did. But, she went to Prom with me in my junior year of high school. Sort of made up for it. 
Chances are, if you had kissed her in grade school, the worst you would have gotten was a slap, or a talking to from the teacher if she wasn't offended and the teacher was (and your parents told, maybe).
Nowadays, you'd have been branded with sexual assault allegations (even if she didn't mind).
That has really gotten freaky out there, and was why we sent our granddaughter to Parochial school. She has always been openly affectionate. In the Public Schools if she'd hugged a fellow kindergartner and they'd replied with 'Ewww!" or something similar, the handbook said the kids would be written up for sexual assault.
