Along with those vibes you're throwing out, men are attracted to something else you put out there - your scent. Perfume and your own body's natural scents - good and bad - have an impact on the chemistry a potential partner feels with you. In fact, in a Cosmopolitan survey, 84 percent of men surveyed said perfume had the power to turn them on or off. They ranked sweet scents like vanilla high because of its ability to remind them of childhood days and perhaps make them secure enough to show their emotions. Actress Jennifer Love Hewitt has even admitted to stashing a bottle of McCormick's vanilla extract (yes, the cooking kind!) in her purse to dab behind her ears. Hewitt says men repeatedly compliment her scent. Surprisingly, the scent of pumpkin pie has the same effect. The top fragrances that guys like use vanilla as part of the blend. Citrus ranks high with guys as well, with floral scents ranking last. The first thing you can do to ensure that a scent works for you and your man is to sample it.
