It's a cruel trick of nature that two of our base instincts are eating and having sex. They're both things we do on dates, but often times they do NOT sit well together. There is nothing less sexy than hopping into the sack after a whopper meal which has left you feeling bloated, lethargic and gassy. Starfish position, anyone? Although it's common sense not to eat a burger wrapped in a pizza right before you get down and dirty, we didn't really include our after-dinner espresso in the no-go sex list. In fact, an espresso after dinner is often touted as a great way to aid digestion and BEAT the lethargy that we are trying to avoid. However, speaking to Cosmopolitan, William Chey M.D., a professor at the University of Michigan and advisor to the International Foundation for Functional Gastrointestinal Disorders advises we skip this treat, especially if we already date nerves: "Depending on how much you typically drink, how your body processes caffeine, and the strength of the coffee you're drinking, strong coffee drinks can amplify the nervousness that triggers stomach issues like diarrhea — the last thing you need when getting close to your partner." Yikes, rethinking our entire lives right now.
