"It seems that sexual appetite causes a greater urgency to consume anything rewarding," the authors suggest. Thus, the activation of sexual desire appears to spill over into other brain systems involved in reward-seeking behaviors, even the cognitive desire for money.

"After they touched a bra, men are more likely to be content with a smaller immediate monetary reward," writes Bram Van den Bergh, one of the study's authors. "Prior exposure to sexy stimuli may influence the choice between chocolate cake or fruit for dessert."

The authors believe the stimuli bring men's minds to the present as opposed to the future. "The study demonstrates that bikinis cause a shift in time preference: Men live in the here and now when they glance at pictures featuring women in lingerie. That is, men will choose the immediately available rewards and seek immediate gratification after sex cue exposure."
