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 v**ina, 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 private parts 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 climax 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 climax: Men who drank had a harder time ejaculating (pun totally intended), while women needed an extra stimulation for their grand finale.
