Sex Quotes in The Perks of Being a Wallflower

How we cite our quotes: (Part.Chapter.Paragraph)

Quote #1

Over the summer, [Susan] got a little taller and prettier and grew breasts. Now, she acts a lot dumber in the hallways, especially when boys are around. (1.2.2)

Sound familiar? We all know someone like this. We here at Shmoop having nothing against puberty, but come on, Susan—be classy.

Quote #2

"You pervert." (1.4.18) (1.10.25)

Charlie's sister says this to him twice: once when he inadvertently witnesses a date rape, and another time when he accidentally walks in on her having sex with her boyfriend. Neither of these events were his fault, but she still calls him a pervert. What gives?

Quote #3

Masturbation is when you rub your genitals together until you have an orgasm. Wow! (1.8.2)

So that's what that Divinyls song means… Thanks for the clarification there, Charlie.
