Coffee drinkers have more sex than non-coffee drinkers.

Coffee has been one of the most popular beverages the world over for centuries and is indeed one of the cheapest highs. Ancient Greeks, Romans and other civilizations partook to the drink religiously, with the first coffee shop opening its doors way back in 1475 in Constantinople.

The reasons for consumption vary depending on individuals and culture. However, what has never been in doubt is the aphrodisiacal effect of the drink. Most people know about this for sure. Studies have revealed that coffee can increase your dopamine levels (the ‘feel good’ hormone) and kickstart your metabolism for those looking to melt down some pounds. Not only that, it stimulates blood flow, which consequently stimulates other passions too. Studies show that coffee drinkers are more active sexually than non-consumers.
However, don’t drink too much of it thinking you’ll be a mule in bed: it actually turns the tables on you and becomes a depressant when consumed in large quantities. For best effect, skip a few days and drink it on the D-day.
