According to my Asian sources (somewhat reliable.... hell we do have a population of 1 billion), certain smells help to stimulate the oppisite sex. Fruity scents and light vanilla scents attract females, while the number 1 stimulation for males (oddly enough) was beer. As for *ahem* preperation, I hear the celery is good for the solidy of your "future generation". Ginseing helps with stamina, viagra... well... fairly obvious...
I perfer to drink red wine, mixed drinks, (sometimes vodka, Remmy Martin, Jack Daniels, or Johnny Walker), and other soft alcholic products.
