One of the most effective ways to improve your sex life and avoid boredom is to explore newer ways and boundaries. Discussing your fantasies is a great way to start—as it generates ideas to spice up your bedroom—and also promotes better communication and deeper intimacy.

While most couples are "afraid" to communicate their fantasies to each other, phone sex offers a gilt edge opportunity to speak about these fantasies and helps you understand what you'd eventually feel comfortable with.

"Phone sex is a good time to actually talk to your partners about what they want sexually or what they fantasize about. This is why phone sex operators even exist: There are certain things that when you're face-to-face with a person are a lot harder to talk about, but you want to fantasize about it," said Stephanie Cathcart of Total Lip Service.

"Especially when people have more taboo fetishes, it's a little harder. But sometimes it's the fact that it's something they would never do that turns them on. The phone is a good way to try it out or at least get that outlet."

Callers have numerous fantasies and phone sex operators are typically tasked with making them feel comfortable enough to indulge—asking them to describe in details their fantasies, and how they would love it to happen.

"Some of the best phone sex comes from a conversation where there's a real connection," says an operator at PeachBooth.

"Getting your partner to open up about themselves, or the origins of their fetish and sexual experiences relating to their fetish, is one way to do that," she continued.

British photographer Phillip Toledano revealed that phone sex operators are helping people explore their fantasies. He made the revelation while interviewing phone sex operators for his book, Phonesex. Once the operators can get the caller comfortable, they're usually firing from all cylinders—expressing their sexual desires in the most explicit way.

"My callers are people with a different sexual appetite. Some want total denial of release. Some want to be forced to be in chastity. Others get off hearing a bossy ( and sometimes bitchy) woman tell them they are pond scum," said one phone operator in Phonesex.

"Some call it odd. They call it kink. I find that most of my regular callers form some sort of bond with me— almost an addiction." she continued.

In a society where unusual sexual behaviors are spited, most people are afraid to share their fantasies—while others are just outrightly embarrassed by it. Phone sex operators are helping people actualize these fantasies, no matter how weird.

"Some clients like to hear the sound of your dick slapping against the phone, or tapping your two fingers against the mouthpiece (preferred)... I have fun doing what I do," another operator revealed in Phonesex. "I share myself with individuals who’re not getting what they need at home. I feel like I teach them how to please themselves, by telling them where to put their hands, and how to stroke themselves." he continued.
