Years ago, when the movie "Austin powers, the spy who shagged me" was about to go to theaters, I saw a video, asking people in public, about the word (shagged)? Someone mentioned, if it was Australian, it would be called, "Austin Powers, the spy who bonked me". Im Australian, I heard the word "bonk" for sex, but never used it. Ive used the word "root" (Americans "rooting" for a sporting team, is pretty funny. "I sex for the broncos")
Me and my wife, will quietly say "husband and wife time" if we're trying to be discreet, about doing it later.
Ive heard two other words for it "yung", and "dood", but i haven't heard either word used a second time (both were weird conversations, where i had to figure out what they were saying, without letting them know, i had no idea what they were saying).
Ive also heard people use the word "fuck" for sex. But I think "fucking" is a different kind of sex, the kind of sex that is more "using Someone else's genitals to masterbate", than "making love".
So id like to know, what are the alternative words you use for "sex"
