GUYS: 10 Drinks that will ruin your performance in bed

8. Rum and Diet Coke 

Stay away from aspartame. Aspartame is the artificial sweetener found in a lot of diet sodas and some foods. There are all kinds of links between aspartame and negative effects: cavities, bone loss, obesity. None of those things will get you laid, or make you want to get laid, especially when you learn that aspartame has also been linked to lowering your libido. Add that to its propensity for giving people headaches and all of sudden you have a real recipe for an action-free night (or a much longer drought). Your best bet is to try natural sweeteners instead (like honey!).
