Sex workers and 'sugar babies' reveal what sex for money is really like.

Most people have probably wondered at some point in their adult lives what it would be like to be paid to do the deed.

For all those curious cats, one Reddit thread has decided to uncover the mystery, asking users who had worked in the sex industry the major differences – and major similarities – between having sex with someone you love, and having sex with someone who is paying you.

Some differences were quite obvious, and probably nothing we wouldn’t expect.

“The biggest difference is the amount of drugs everyone is on,” wrote one user.

Other confessions were more profound.

“I’d say the biggest difference is the lack of ability to get comfortable with the other person,” wrote one former sex worker.

“One guy would stay the night with me in hotels and I would wait for him to fall asleep to take my makeup off and wake up before him to put it back on, even after knowing him for months. I wanted him to get what he was paying for, which was me being made up and looking nice all the time.”

Others agreed that being paid for sex often meant you couldn’t “relax” during the experience.

“My boyfriend would never try to gag me or switch holes or pinch me, but the men who would pay me didn’t care. I used to be so tense during sex that I’d be sooo tight. It was very uncomfortable,” said one user.

“It’s so different now. My boyfriend loves me, I feel so safe. I can do things like put my ankles on his shoulders or close my eyes.”

Australia’s highest paid sex worker, Samantha X, has one hard ‘no’ when it comes to sex with clients. She talks to Mia Freedman about it, on No Filter. Post continues after audio.

Others confessed that their real-life lovers got the “unfiltered, real version” of themselves and that reaching orgasm doesn’t have to be only aim.

Perhaps the most surprising confessions came from those who admitted that paid sex was sometimes a more satisfying and intimate experience.

“The thing that might surprise people is that I don’t ever feel degraded or shitty about myself for doing [sex work],” said one user.

"When I was younger I dated guys in my personal life that treated me like absolute garbage and I got nothing emotionally or fiscally out of it. This guy [who pays me] listens to me, is kind, gracious, just is really one of the nicest people I've ever been with."

Another shared that they were "far more affectionate" with their 'sugar daddies' than their real-life boyfriends.

"Many older men want a sugar baby because they feel lonely - their relationships have fizzled out and their children have grown up and moved away. They turn to sugar babies not just to satisfy their sex drive, but to fulfil their need for intimacy and affection," she wrote.

"When I have sex with a sugar daddy, therefore, my goal is to make him feel like I’m almost in love with him... It’s far more gentle, there’s a lot more kissing involved and my focus is 100 per cent on his desires."
