Now it's okay to go for seconds on that pumpkin pie!

The Smell and Taste Treatment and Research Foundation recently released a study examining how scent impacts arousal by measuring increases in penile blood flow. Pumpkin was found to be one of the scents that stimulated men most, increasing blood flow by 40%. Other smells provoking arousal were doughnuts, lavender, black licorice, cola, lily of the valley, buttered popcorn and cranberry.

So fill up your man's plate with an extra large slice of pumpkin pie with a side of cranberries at this year's Thanksgiving feast. This is the perfect recipe for some holiday post-feast passion. For more information on the study, visit ScienceofSmell.com.
