5th grade - Not sure why, but it was girls only. Had a bunch of my fellow classmates unable to control themselves for weeks just giggling and running away from boys. It just made the boys real pissed off at the girls for the rest of the year.
6th grade - Everyone got it this time, but now the boys were avoiding girls. The kids who called themselves (couples) contemplated sex lolol. Don't think anyone actually did it.
7th grade - Yet again everyone, but this time we watched videos concerning Internet safety, the benefits of abortion (made a lot of kids uncomfortable, I won't lie.), pedophilia, the works...STDs...also, quote of the year : "If you just orgasmed, and then pee'd right after, there's no way the leftover sperm can get anyone pregnant. Besides, why the FUCK WOULD YOU WANT TO PISS IN A GIRL?!"
8th grade - Punched both guys and girls when they started spreading rumors about perfectly clean people boning each other. Fun year.
