I heard my mom talk to my aunt about my cousin, so I talked to him about it. My friends and I talk about sex (I might be a conservative teen, but I’m a teen) with my friends.
You talk to your friends about sex acts? Feltching, rim jobs, prolapsed rectums, Hep C, drug-resistant gonorrhea?
Really?
Even if true, you're talking about it as teens, who know, really, nothing about life.
To reiterate, I will pray that at some point you'll realize how little you know. It's called humility, and it's a (gasp) Christian virtue.
