Most women have caught their partner's eye wandering when an attractive woman walks by. No matter how monogamous and faithful, the visually stimulated heterosexual man is “naturally programmed” to want more than one woman. Dennis Prager, speaking for the online non-accredited academic institution Prager University, claims a man’s “built-in” attraction to the female body is all due to evolution, and at the end of the day, “he wants you.”

“Even men in happy relationships will still find some women more attractive than their own girlfriend,” Prager says in the video “He Wants You.” Prager contests men are inclined to look at other women simply because they are other women. Although they are excited by other female forms, this does not mean they are dissatisfied with their own partner, however.

Although Prager’s statements can be ludicrous and at times misogynistic, his explanation does hold scientific merit. A 2013 study published in the journal Archives of Sexual Behavior found unlike women, men prefer faces they’ve never seen before when it comes to being visually stimulated. Men rated these women less attractive when they saw them for a second time. Researchers believe the reason may be that men evolved to maximize their reproductive success by mating with as many partners as possible, which explains the Coolidge effect of why men are aroused by the idea of a new sex partner than women.

"Men are programmed by nature to want variety, indeed endless variety,” Prager says. However, he assures insecure girlfriends that if their relationship with their boyfriend is solid, they have nothing to worry about. Prager suggests for women to do away with their primal fears of losing him and realize men may ogle women, but once they are out of sight, they are out of mind.

“More than anyone else in the world, he wants you. And if you don't believe me, ask him,” Prager says.
