There are sluts for each grade
Um no
13-year-old vagina is off the radar, unless it's one of those 12-year-old girls with a nice ass and tits bigger than normal girls do... they should be legal.
Also, barely any homework in Middle School.
EDIT: I have been perverted since I was like 6. I remember in second grade I used to talk about braiding pubic hair with my friends Jason and Victor.
