The Surprisingly Simple Way To Seduce Him This Halloween. (It Doesn’t Work on Her.)

Forget oysters, Vitamin E, and even a glass of bubbly. Research reveals that the sexiest aphrodisiac of all may be round, squishy and . . . orange.

Alan Hirsch, M.D., neurological director of the Smell and Taste Treatment and Research Foundation in Chicago, invited a group of 30 women to sit in a lab, attached to a device that measures vaginal blood flow, and sniff 30 different odors, ranging from licorice to gooey cheese pizza. He also asked a group of (oddly cooperative) 31 men to sit in a laboratory, their penises attached to a machine that measures blood flow and sniff the same 30 scents.

The surprise? The big winner for most arousing smell — pumping the penile blood flow by 40% — was the mingled scents of pumpkin pie plus lavender. The runners-up were doughnuts with black licorice (32%) and pumpkin pie with doughnuts (20%). (Leading Guru to wonder how many cops participated in the study.)

Women are a different story. Number one turn-ons: the mingled aromas of cucumber and licorice; and the sweetly innocent scent of baby powder. (Remember Love’s Babysoft cologne, a big hit of the seventies?)

A Halloween heads up to the guys: Three scents actually turned women off: cherries, barbecued meat and men’s cologne.
