1. Taking an Antihistamine: Antihistamines work by drying out your mucus membranes to relieve nasal congestion… and in doing so, can also dry out other parts of your body, especially the va gina, says Nicole E. Williams, M.D., board-certified gynecologic surgeon. Long story short, no matter how turned on you might be, your vag will not get the memo.
2. Eating Spicy Foods “Foods can affect vaginal odor and taste,” says Kathryn Boling, M.D., primary care physician at Mercy Medical Center. Super-spicy foods like jalapeños can cause gas, bloating, and farts that just won’t quit. What’s worse, the residue left on your hands and in your mouth post-nosh is notorious for setting genitals on fire.
3. Drinking Too Much Sure, light drinking can put some people in the mood, but overdoing it can dull your senses—and may send your big O packing. “Since alcohol is a known depressant, your ability to experience an orgasm may actually be diminished if you’re too buzzed,” says Williams. In fact, one study at the University of Missouri-St. Louis found that 11 percent of alcohol users had problems achieving orgasm: Men who drank had a harder time ejaculating (pun totally intended), while women needed an extra stimulation for their grand finale.
