The Smell & Taste Treatment & Research Foundation conducted a study to see which aromas had more of an -ahem- arousing effect on men.
So, what was the top 'arousing' fragrance from this study? A combination of pumpkin pie and lavender! While I can't personally vouch for the effect on the male anatomy, the fragrance is wonderful-- spicy sweet pumpkin mixed with the warm, distinctive floral of lavender.
