You’re not going to like what you’re about to hear: According to a new Czech study, 72 percent of women in long-term partnerships dream about other males they know.

According to a University of Vermont study, the longer you spend with her, the more her mind wanders.

But, before you panic, keep in mind that her private lust for another man doesn’t necessarily mean your relationship is doomed. There’s no empirical proof that her contemplation of cheating will result in her doing so.

Wendy Walsh, Ph.D., an adjunct professor of psychology at Cal State, says fantasies are just a way for her to satisfy a primitive desire for sexual variety while remaining true to you.

“Novelty and newness excite human beings,” Walsh adds. “Spreading our seed is part of our anthropological mission. Sexual fantasies allowed her to generate that newness in her mind instead of in her bed.”

It doesn’t imply she doesn’t care about you, according to Walsh. It will help her remain loyal by satisfying her curiosity without really breaking any boundaries.

“The number one thing that helps monogamy survive long term is fantasies,” Walsh says.

Plus, you’re always doing the same thing. According to a study conducted in Vermont, 98 percent of men fantasize about having sex with other women. (We believe the remaining 2% are liars.)

The final line, according to Paul Hokemeyer, Ph.D., a marital therapist in New York City, “don’t sweat it.” Hokemeyer advises, “Appreciate the fact that she gets aroused and wants a full and exciting sex life.”

But bear in mind that dreams aren’t the only method to make sex in a long-term relationship interesting.
