While working as a high-class escort for nine years, Rebecca Dakin saw hundreds of married men turn to her to fulfill sexual needs not being met by their wives.

In 2009, she switched gears professionally and became an infidelity counselor, using her experience as a call girl to teach women about how to satisfy their husbands.

"I’ve spent years hearing men tell me why their relationships failed and why they slept with escorts or other women," the 37-year-old Brit told The Sun. "I know better than anyone just what it is that women do that drives men away.”

Dakin says that the number one reason men look outside of their relationships for sex is because they're not getting enough of it at home.

According to Dakin, other reasons for infidelity include a need for thrill or excitement, feeling bored by the sex they receive from their partner or feeling hesitant to share their intimate desires and fantasies with their spouse.

And it appears that research backs up Dakin's hypotheses. According to "The Normal Bar," an extensive survey of 100,000 people published this year, 71 percent of unfaithful men and 49 percent of unfaithful women said sexual boredom was the reason they cheated in their relationships.
