Beans
Beans are a pre-sex no-no not just for the gas factor—they also make you super-bloated. Beans contain a sugar that isn't digestible, according to a study published in Nutrition Journal, so once they hit your stomach you're sure to puff up.
Red Meat
While a steak dinner might sound like a romantic date, eating a fatty piece of red meat causes your body to go into overdrive when it's time to digest it, which can end up making you feel super sleepy—aka not ready for action.
Cheese
Seventy-five percent of people in the world are lactose intolerant. (Crazy, right?!) Since most of us have trouble breaking down dairy products like cheese and milk—because they contain the enzyme lactase—you might want to skip having pizza on a big date if you'd like to avoid gas and bloating later.
Gum
Okay, so it's not technically a food, but it's important to know that while chewing gum might give you kissably-fresh breath, all of the air you're swallowing while smacking away may also give you gas, according to the Mayo Clinic. And that could kill the mood no matter how minty your mouth is.
