3. Your birth control pills can cause vaginal dryness.

Menopause may be years away, but lately, even when you’re totally in the mood, your vagina is more like the Sahara desert than the waterfall it used to be. While not typically the case, some women experience this distressing side effect from hormonal contraception.

4. Your vibrator won’t mess with your pacemaker:

No way do you want to tell your cardiologist that you are terrified that sex with your regular partner, “Bob” (AKA your “Battery Operated Boyfriend”) will cause a pacemaker malfunction. Rest assured, vulvar or vaginal vibration will not “unpace” your pacemaker.

5. Using vaseline as lubricant can cause recurrent vaginal infections.

Vaseline makes your chapped lips feel so much better, so it stands to reason that it would be the perfect product to keep your other lips moist as well. But unfortunately, petroleum jelly has been shown to double the chance of bacterial vaginosis, the most common cause of odor and irritating vaginal discharge. Instead reach for a silicone lubricant like Replens Silky Smooth when the time comes.

6. Infertility treatments don’t have to ruin your sex life.

You are not imagining it. Sex with a purpose, takes the sexy out. A 2012 study out of the Indiana University School of Public Health confirmed what most couples have already figured out — assisted reproductive techniques, especially IVF, cause problems with sexual desire, interest, and satisfaction. As expected, “mood-type symptoms” that could be attributed to the stress of going through fertility treatments, like sadness and anxiety, were huge, but the study also found that women had physical issues such as vaginal pain and dryness.
