Industry insiders like to say that they’re seeing more “normal” people, girls “with good minds.” Mike of A&M Studios, a producer of X-rated video chats, says: “A couple years ago, we’d have a lot of strippers or people who might be on meth — a lot of shiftier people.” He continues, “Now we’re seeing performers who are more educated and used to working on a regular schedule. There’s been a shift to a very different class of people.” Much as his phrasing gives me chills, it isn’t just a cliché that women with limited job opportunities often turn to sex work.

The difference in these dark days is that middle-class advantages, like a solid college education and professional work experience, don’t offer the same level of protection that they once did from being pushed to make such a choice. Not to mention, it’s easier now to make the decision because the Internet has bulldozed the barrier of entry into the sex industry. Just a few clicks away from Craigslist’s job board is an array of immediate, cash-upfront adult gigs.

Last month, it looked like that might change: Craigslist announced it would replace its raunchy erotic services section with a costlier and human-monitored “adult” section to appease a threatening state attorney general — but, so far, the only difference is that there are fewer ads and more euphemisms. Instead of hand jobs and BJs, women offer “sweet treats,” “pleasure,” “play” or, most popular of all, sensual or erotic “massage.” Those looking to hire simply put out a call for a “personal assistant” or a “female teacher” under “adult gigs.” Craigslist still allows “normal” girls like Marie to easily gauge the going rates, pick up the lingo and become plucky entrepreneurs, so long as they have Web access.

It took me all of five minutes, and a couple of hesitant keystrokes, to create a Craigslist account, verify my phone number and submit a fake adult ad reading, “Looking for some fun? I’m a 30-year-old professional woman who recently lost her job. Now I’m offering top notch sensual services. E-mail for details.” An hour and a half later, the posting was approved and a $10 fee was charged to my credit card. The next time I checked my e-mail, I had 68 enthusiastic inquiries, and a photo of a penis, waiting in my in box.

Like a blogger or message board troll hiding behind a handle, I felt safe and unaccountable in my anonymity. I could lean back in my chair and detachedly watch my solicitation bobbing in a sea of nearly 100 other local adult ads. Some argue that prostitution always requires a certain level of disassociation — letting your brain vacate and your body drive — but the online marketplace allows for that on a whole new level. Our cultural hooker hard-on has also made selling one’s body more tenable. In the age of Sasha Grey and “The Girlfriend Experience,” “sexting,” “Secret Diary of a Call Girl,” Ashley Dupre, courtesan bloggers and strip aerobics, so many girls and women are already flirting with the idea of sex work. Nowadays, it seems we’re capable of looking at prostitutes not just with pity, but sometimes admiration — particularly escorts whose work affords snazzy clothes, designer handbags, fine dining and world travel. (Never mind that those women are largely mythical: As an upscale sex worker told Salon after watching Showtime’s “Call Girl” series, “Guys aren’t going to pay $1,000 for pussy.”) That’s not to say that it’s socially acceptable to have sex for money, but we’re so much more familiar with the idea these days. In fact, Hollywood has walked so many miles in working women’s stilettos that HBO is turning to the opposite gender to give sex work some edge: In late June, the channel debuts “Hung,” a series about a high school basketball coach who becomes a male escort. We know — or think we know — all about sex work, how it looks and what it feels like. The truth, according to most of the newbies I spoke with, is that it’s much harder than they expected.

Take 55-year-old Jennifer of the Bronx, N.Y., who was laid off from her financial bookkeeping job: She talks about her entry into sex work with the shell-shocked detachment of someone who’s recently lost a loved one. “It’s hard. It’s an awful thing to have to do.”

“How do you cope, considering you can’t turn to your family or friends?” I ask. Suddenly, there are sobs on the other end of the phone line and the rhythmic sound of air being sucked in. It almost sounds like she’s hyperventilating. “You’re the first person I’ve told,” she says. Moments later she has to excuse herself to blow her nose.

Her husband, a subcontractor, also got the boot five months ago. He managed to find a part-time gig but, despite three decades of work experience in her field, Jennifer hasn’t been able to land anything. Meanwhile, bills have piled up and they’re six months behind on their mortgage; that’s why Jennifer started turning tricks on Craigslist.

Jennifer’s family thinks she has a temp job. She uses the same computer she shares with her son to post her ads online and e-mail back-and-forth with clients. Jennifer methodically deletes her browser history (although she worries about whether her son can read her e-mails). Her marriage, on thin ice for some time, is now submerged in frigid waters. Sometimes she starts fights with her husband, just so he doesn’t get close enough to pick up another man’s scent. “I feel like the family would disown me if they knew,” she says.

Some women wade into the cesspool instead of diving right in. Alicia started doing adult modeling after losing her job last July as a nutritionist near San Francisco. The 23-year-old single mother masturbated for men in gnarly budget hotels for four months, lying to her boyfriend and living as “two people.” Eventually she was doing POV shoots where a guy — “older than my dad,” she says — would finger her while taking photos. Then, last month, she found a full-time job as a waitress and, much to her relief, hasn’t seen the inside of a roadside motel room since.

Like most of the women I spoke with, Alicia wasn’t willing to ask for financial aid or a place to crash from her family or friends. For her, it was a matter of pride, of independence, not to mention control. For them, slinging burgers at a fast food joint means you’ve really hit bottom, while sex work at least allows for the illusion of being in charge. Looking back, Alicia found that calculation didn’t exactly compute: “Sometimes I’m like, Dude, why didn’t you just get a job at McDonald’s? It’s a paycheck,” she says, slipping into the second person. “But you were at a point in your life where you had zero money to put food on the table. You had to do what you had to do. It’s a survival thing.” Not to mention a money thing: When it comes to a paycheck, turning tricks trumps minimum wage.

After a while, even I began to wonder what kind of cash could be made — after all, I wouldn’t mind paying off my credit card bills and medical debt. Ken Viper of Viper Entertainment, an X-rated Web cam company, waxed poetic to me over the phone about how one of his girls got paid $1,400 for an eight-hour virtual date in which she ate popcorn and watched a movie. After calling me “babe” for the umptillionth time, he proclaimed: “I haven’t even seen you, but just from talking, I know you’d do great.” Later, speaking to his colleague at another Web cam company, I found that my reputation preceded me: “Ken told me, ‘She sounds hot! You should get her to work.’” I won’t lie: For a moment, I contemplated making mad money while talking to lonely divorcés and noshing on microwavable popcorn. (As they say, every woman has her price. Perhaps mine is popcorn.) Just like when you hear about women selling their eggs or auctioning off their virginity for large sums of money, it’s difficult not to greedily run the numbers in your head. One Web cam operator told me point blank: You could make three times your current salary.

These Tony Robbins-esque industry pitches have an obvious seductive allure. It’s like a late-night infomercial that promises to make your dreams of becoming a millionaire, or having blindingly white laundry, come true. (Buy now for the low price of — well, the cost is different for every woman, now, isn’t it?) When the responses to my faux-adult ad started rolling in — at a rate of roughly five an hour — I reflexively calculated the potential income with dollar signs in my eyes. It can seem like a “get out of jail free” card, a lottery ticket, a get-rich-quick scheme.

But the recession reminds us that there are few quick fixes, and there is no get-out-of-jail-free card. For the women I spoke with, sex work was like bailing water out of a leaking boat: You stay afloat, so long as you don’t stop.

More and more, Marie seems to be reconsidering her position. One week she was giving a married man a blow job in his car, the next she was turning down a “sensual massage” client because he demanded sex before she offered it. She was signed on to film a porno, but pulled out when the director, and his roaming hands, took personal license with her body. For a few weeks, she talked about getting a professional massage table, so that she could continue doing physical therapy, without the extras, until she landed a corporate job. Now, she’s looking for gigs cleaning men’s houses clad in a teddy. But if that doesn’t work out, a $10 sensual massage ad on Craigslist will net a guaranteed 75 bucks. As prostitution advocate Margo St. James once said, “A blow job is better than no job.”
