Dan Savage, the syndicated sex advice columnist, refers to “the four magic words” gay guys will use during a sexual encounter: What are you into?” That’s a very different perspective than that of straight boys, who usually aim for one-word assent to options they define. I do fear, though, that since girls, as I’d previously found, are so often disconnected from their bodies’ desires and responses, their answer to an authentic conversation-starter might well be, “I have no idea.” What might happen, though, if teenagers learned to start talking to each other that way early on?

Absent guidance from trusted adults, boys look to the media as a default sex educator, where they are bombarded by images of female sexual availability and male sexual entitlement. With the rise of the internet, smartphones and video-sharing sites like Pornhub, parents worry about the potential impact of pornography on teens’ sexual expectations. Let me be clear: Curiosity about sex is natural. Masturbation? Great! What’s more, there is all kinds of porn — ethical porn, feminist porn, queer porn. But the most readily available, free content portrays a distorted vision of sex: as something men do to rather than with a partner and women’s pleasure as a performance for male satisfaction.

Boys frequently expressed ambivalence to me about their porn habits. “I think porn affects your ability to be innocent in a sexual relationship,” a high school senior commented. “The whole idea of exploring sex without any preconceived ideas of what it is, you know?”

Even if parents could block all the triple-X sites (and good luck with that), the reality is that exposure to sexual content in media consumption of any kind — TV, movies, games, social media, music videos — is associated with greater tolerance for sexual harassment, belief in rape myths and the objectification of women. “I think music has some of the biggest impact on how guys treat girls,” another high school senior told me. “In the car, my friends and I listen to all this stuff that’s just” — he rattled off several oh-so-unprintable lines about women and sex. “When you hear that, like, five, six, 10 times a day, it makes it hard to escape having that mind-set.”

The promise of hot sex with a cold heart animates college (and increasingly high school) hookup culture — which is why, according to Lisa Wade, a professor of sociology at Occidental College, getting wasted beforehand is so crucial: Alcohol girds young people against the near-fanatic generational fear of the awkward while creating what Ms. Wade calls the “compulsory carelessness” necessary for a possible one-off. Most of the guys I met knew that sex with an incapacitated person is assault. Yet because, in their minds, you need to be hammered in order to hook up, the trick became being (and finding someone who is) drunk enough to want to do it but sober enough to be able to express a credible “yes.” And who is to be the judge of that?

Drunk boys, as it turns out, tend to vastly overperceive a girl’s interest in sex, often interpreting expressions of friendliness as It’s on. Alcohol has also been shown to diminish their ability to hear “no” or notice a partner’s hesitation. Wasted young men are more likely than they would be sober to use coercion or force to get what they want and — still looking at you, Brett Kavanaugh — they are less aware of their victim’s distress.

In consensual drunken hookups, the sex still tends to be meh. It “can feel like two people having two very distinct experiences,” a second-semester college freshman who’d had multiple partners told me. “There’s not much eye contact. Sometimes you don’t even say anything. And it’s weird to be so open with a stranger. It’s like you’re acting vulnerable, but not actually being vulnerable with someone you don’t know and don’t care very much about. It’s not a problem for me. It’s just — odd. Odd, and not even really fun.”
