It was 5th grade.
People didn't start talking/joking about it until 7th grade.
Parents talked to me about sex with girls and stuff but not really this subject. I literally thought I had invented some shyt

I was like "this could stop teenage pregnancy."
Remember this white chick in 6th grade math was putting her hand on my thigh and rubbing it while taking my hand and trying to get me to finger her in class. Logistics made it impossible since she sat on my left and I write left handed (breh still gotta take notes).
Good times
