No. 10 - A Breast-feeding Woman

Molly Edmonds, HowStuffWorks.com

If what we see in romantic comedies is true, then there's nothing more arousing to a single woman than attending a wedding alone. As the movies would have it, every available man from that point might as well be wearing a gigantic bull's-eye.

But according to a 2004 study conducted by researchers at the University of Chicago, the real aphrodisiac for women is the smell of a new mother and her baby. Women were given pads used by women while breastfeeding to smell. When smelling the pads used by lactating women, women who already had partners reported a dramatic increase in sexual desire, while single women experienced an increase in sexual fantasies. Smelling a fresh pad, untouched by mom or baby, did nothing for the women's sex drives.

If a breastfeeding mother doesn't smell like romance to you, perhaps other items on our list will pique your interest.
