Myth #1: You can’t get pregnant if you do it standing up.
Fact: Sperm are Olympic-class swimmers with a single-mission mentality – find the egg and fertilize it.
The myth’s underlying assumption – that it’s harder for sperm to swim against gravity, making it more difficult for you to get pregnant – is wrong,” says Aletha Akers, M.D., MPH, assistant professor of gynecology at the University of Pittsburgh School of Medicine. “Sperm can swim in any direction, and they swim pretty darn fast.”
Myth #2: You can’t get pregnant if he pulls out.
Fact: You’d think that if a guy doesn’t ejaculate inside you, there would be no sperm to hook up with the egg. Wrong.
Men produce a tiny bit of liquid called “pre-ejaculate” that’s teeming with sperm. They can release it any time during sex without even realizing it.
Even if your partner pulls out right before ejaculation, he’s probably already deposited sperm, Akers warns.
Myth #3: Douching is the best way to keep clean down there.
Fact: About 20%-40% of women douche – and half do so weekly.
But the best way to keep your nether region clean is to leave it alone, gynecologists say.
“People think it’s like cleaning any other part of your body, but your vagina has its own self-cleaning mechanism,” Akers explains. “It produces its own fluids that help to wash things out while also keeping the right bacteria around in the right proportions.”
Homemade or store-bought douches (usually solutions of water, vinegar, baking soda or iodine) upset the vagina’s natural bacteria balance and increase the risk for yeast and other vaginal infections.
Because douching can push bacteria from the vagina higher into the reproductive organs, it may also contribute to pelvic inflammatory disease, a major cause of infertility.
Myth #4: You can get herpes only if you have sex when your partner has an outbreak.
Fact: Transmission risk is highest during an outbreak, but because carriers can always shed herpes virus, they can also infect their partners at any time during unprotected sex, says Ashlyn Savage, M.D., assistant professor of obstetrics and gynecology at the Medical University of South Carolina in Charleston.
According to the Centers for Disease Control and Prevention (CDC), 11% of men and 23% of women have genital herpes; 56% of men and 60% of women have oral herpes, which can spread to the genitals through oral sex.
To prevent its spread, avoid sex during outbreaks and always use condoms for intercourse and dental dams for oral sex.
Won’t condoms protect during an outbreak too? Not always.
“Herpes is a skin infection, not something transmitted by bodily fluids like HIV or gonorrhea,” Savage says. “If either partner has an open sore outside the area covered by a condom, they could transmit herpes even with a condom.”
Myth #5: If you’re aroused, you shouldn’t need lubricant.
Fact: Needing more lubrication than your body produces doesn’t mean you’re not aroused.
“A lot of people equate wetness with how turned on they are, but that’s not necessarily an accurate barometer,” says Anne Semans, co-author of Good Vibrations Guide To Sex (Pleis Press).
Your monthly cycle, pregnancy, illness, menopause, medications (such as antihistamines and decongestants) can affect lubrication, no matter how much water you drink.
And if you’re using condoms – including lubricated ones – you’ll need extra lube.
Latex doesn’t slide well even if you’re naturally lubricated, Savage says.
Myth #6: You can become addicted to your vibrator.
Fact: Even if you climax faster and more easily with battery-powered assistance, a vibrator won’t ruin your ability to achieve orgasm with your partner, sexperts say.
“We can still have orgasms if we take the time, but we’re so used to the quick response we get from the vibrator that we get impatient and give up,” says Ellen Barnard, a sex educator/counselor and co-founder of A Woman’s Touch in Madison, Wisconsin
