The truth is my mother and I grew up in different worlds. My mom was born in 1942, in the middle of World War II. My mother grew up in a world where no one talked about sex. Where sex was secretive and sex was racy. She grew up in a world where sex meant marriage. Where women waited to kiss a boy until they were going steady. My mother grew up in a world where a woman couldn’t eat dinner alone in a restaurant, lest she look like a prostitute. She came of age in a universe without easily available birth control, without abortion, without options. My mother wore poodle skirts and twins sets, and had a black-and-white TV. She never witnessed a young Britney Spears pulsating in a bikini musing on her virginity (or lack of).

My nymphomaniacal grandparents were perhaps not typical of their generation, and we cannot discount the effect that my nymphomaniacal grandparents must have had on her.

I grew up in a world that was just the opposite. I grew up in a culture obsessed with sex. My childhood was punctuated by salacious New York Post headlines. As a girl I remember watching the Anita Hill-Clarence Thomas hearings on CNN. I was sitting in my mom’s bedroom, playing with stickers and asking her what a “pube” was.

The 1980s in New York City were a time of contradictions — a time of limousines riding by homeless people, a time of the richest and the poorest as neighbors, living side by side, stealing from the other. The city was boiling with rage, with fear, with crime, and with sex. Sex was everywhere — from sex crimes like the Central Park Jogger case to Donald Trump’s divorce from Ivana, to sex clubs like the Vault. Back then pornography was on basic cable (it was on channel J). Sex was everywhere.

Sex was piped into our lives through the media. The library was popular because it housed “Tiger Eyes,” which was the dirtiest of the Judy Blume oeuvre. From books to TV, my teenagehood was hugely influenced by the musings of Aaron Spelling with his “Beverly Hills 90210″and “Melrose Place.” I watched reruns of “Three’s Company” –  which was filled with innuendo and sexual hijinks that would have been considered pornographic when my mother was a girl. No matter how unsexy a show was, it seemed they always dedicated at least one or two episodes to teen pregnancy or STDs or date rape or some other “sex”-related theme. There was the usual media schizophrenia about sex, but whether it was promoted or profane the topic was still very much in the forefront.

But by 1988 AIDS was just starting to be picked up by the mainstream media. The thing that affected every single girl on the Upper East Side of Manhattan was the AIDS infection of Ally gertz. Ally gertz had been a popular girl who had gone to a private school and did everything right … Everything right, until she met a cute bartender at Studio 54. She had one one-night stand, and from that she became infected with AIDS. She became a one-woman mission for AIDS awareness. She was a hero, but she was also a victim.

Soon after, someone decided that talking about sex would keep kids from having it, or if they did have it, they would have it safely. People were always asking me if I wanted to talk about sex. I endured hours of school sex education lectures. I went to a very progressive middle school where they had our eighth grade classes go out to the local CVS to buy condoms. The hippy ideal behind this misadventure was that if we were not embarrassed we would be more apt to go off and buy condoms and use them.

My two dorky best friends and I bravely walked down West Eighty-eighth Street. We bravely went into the drugstore. My friend Stephanie was not the type to suffer fools gladly. So as we giggled insanely she took the bull by the horns and bought the prophylactics.

Later we unzipped our backpacks and placed the condoms in the center of the large wooden table. The teacher congratulated us for our courage and ability to remove money from our wallets. We then proceeded to open the condoms and put them on bananas. Even at the tender age of twelve we understood how profoundly misguided our teachers were. We weren’t stupid idiots. We knew how to go into a store and buy things. Most of us smoked at least a few cigarettes a day by twelve years old. We weren’t short bus riders. Kids have unsafe sex because they think they are invincible not because they are too stupid to buy condoms. It did not create a class of safe-sex zealots, as I think our teachers might have hoped. It did, however, make sex seem somehow unsexy.

I am my mother’s worst bourgeois nightmare. I live on the Upper East Side. I have three children — all by the same man! I never slept with a man who wore cowboy boots. I have never been to a sex club. I have never had a Dominican divorce. I did, however, go to rehab, but that is for “the most drugs I ever had” anthology or possibly “the where did my teens go” anthology. I am a low-rent yuppie, shuttling my children back and forth to the various and sundry activities and involving myself in the Parents’ Association. I am the person my grandmother and mother would have watched in silent scorn. I sometimes tell my children that my most important job is taking care of them. I am not saying that I am a better mother than my mother. In fact, I am probably a worse mother than my mother, but I am a more traditional, or should we say, repressed mother than my mother. For example, in this book the great and talented Julie Klam tells her daughter to call her vagina her front. She shows this as an example of her repression. I call this an example of her brilliance.

Maybe I would have been more slutty, if I hadn’t grown up watching my mother saunter around our town house au natural, past the pictures of naked lesbians fooling around. Or maybe it was all the book readings I went to growing up. Or possibly it was the trauma of sitting through my mother’s fourth wedding and listening to my mother call my stepfather a “horny Boy Scout.” It was a phrase I did not soon forget. In fact it still haunts me to this day.

There is also a slim but real chance that this is just who I am. That growing up surrounded by sex did not make me a prude. Though it is true that my mother’s generation needed to rebel, to free themselves. Whereas my generation was already free. There was no need for us to fight the power because we were the power. We were the advertising dollars that the consumer goods industry fought for. We had all the rights we needed and possibly more. We didn’t need to fight for birth control. We didn’t need to fight for the right to choose. We didn’t need to fight for the right to vote. There was no reason for us to feel guilty about having sex before marriage. There was nothing to fight against. We didn’t need to burn our bras, so we burnt our CDs. And perhaps that’s why I’m neither a lover nor a fighter.

Molly Jong-Fast wrote about her wild life as a girl in 1990s New York in a novel, “Normal Girl,” and a memoir, “Girl [Maladjusted].” Her third book, “The Social Climber’s Handbook,” came out in April 2011 from Villard/Random House. She lives in New York City with her three children and two lizards, and her husband who does not like to be written about, at all, ever.
