Bacterial vaginosis, or BV, is the most common vaginal infection among people 15 to 44 years of age. It’s caused by an overgrowth of harmful bacteria, such as Gardnerella vaginalis. A healthy vagina hosts thriving populations of Lactobacillus bacteria species, but when these “good” bacteria are crowded out by certain types of “bad” bacteria, the vaginal ecosystem can be shifted, causing BV.

There is a lot of confusion about BV. Is it a sexually transmitted disease (STD)? What are the symptoms? How can you avoid it?

All good questions. Let’s examine them one by one.

Is BV an STD?

The consensus seems to be that BV isn’t officially an STD, but even reliable sources have somewhat contradictory information. Planned Parenthood doesn’t list BV as an STD on their informational webpages. The Centers for Disease Control and Prevention (CDC) does include BV on their STD website, but also says that “BV is not considered an STD.”

On the other hand, the Office on Women’s Health says that “BV can … be caused by vaginal, oral, or anal sex” and that “you can get BV from male or female partners.” And there’s an entire chapter devoted to BV in the premier medical textbook on STDs, and its authors say that, while sexually inexperienced females can get BV, “the weight of evidence supports sexual transmission” of G. vaginalis, the bacteria species most famously implicated in BV infections.

The same webpage on which the CDC declared BV not to be an STD also says that it can be transferred between female sexual partners. Indeed, women who have sex with women have higher rates of BV. Since vaginal fluid could spread BV, partners can change condoms when a sex toy is passed from one to another, and use barriers like dental dams when engaging in cunnilingus (oral contact with the female genitalia) or rimming (oral contact with the anus).

What about heterosexual transmission? Continue reading

Teen Talk: Am I the Only One Not “Doing It”?

holding hands from backSometimes, it seems that everywhere you look, young people are having sex. In the movies, on television, in songs; love and sex are all the thing. Are you the only one resisting? Are you the last virgin on the planet? Should you say yes to sex?

First, let me reassure you not all teens are engaged in sexual relationships. Even if many of your peers seem to be talking casually about sex, that doesn’t mean they are actually having sex! The latest surveys have shown that fewer than half of high school teens, 47 percent, have ever had sex. The average age for teens to first have sexual intercourse is 17 years old. And many teens are waiting even longer.


Saying no can be hard, but liberating at the same time.


Sex is one of the most wonderful and intimate experiences you can have with another person. But there is so much to consider before you let your emotional feelings lead you to do something you are not ready for emotionally or physically. Feeling pressured into sex or having a sexual encounter too early can make someone feel uncomfortable, upset, and maybe even regretful or sad. Peer pressure can be strong, especially if you think all your friends are doing it, or if your boyfriend or girlfriend is urging you without listening to your side.

So how do you know if you are ready for sex? And if, after careful thought, you decide you are not ready, how do you say no? Continue reading

Teen Talk: The Truth About Tampons

tamponsIf you had told the 13-year-old version of me that someday, I’d be writing about tampons on a blog, my first reaction would be, “Eww, gross!” But here I am, writing about tampons. Life can take you in unexpected directions.

When I was growing up, tampons had a mixed reputation. There were those people who thought that tampons would somehow make you lose your virginity. Then there were fears about infections, or the chemicals that were used.


In a school or in a pool, tampons are safe and pretty cool.


Me, I was just worried they’d hurt, and I never wanted to use them. My refusal to use a tampon meant that I couldn’t go swimming in gym class — and everyone knew that I was on my period. There I was, sitting in the bleachers as everyone else was splashing around. I knew I wasn’t the only one who didn’t want to wear a tampon — during lunchtime, a few of us quietly talked about our fears, but none of those other girls joined me on the sidelines. I think they were more concerned about their classmates knowing their business. During our six-week swimming unit, only a few girls sat out their periods in the bleachers.

Tampons weren’t the right choice for me at that time, but for other girls, they were convenient and comfortable. If you’re curious about tampons but have some concerns, it might be worth looking into them so you can make an informed decision. I’m glad we have so many options to deal with our periods — my mom would tell me about these crazy belts with buckles or pins that they’d have to put up with every month. But you have a ton of things to choose from when finding the products that work best for you. Continue reading

Teen Talk: I Can’t Get Pregnant … Can I?

teen pregnancy testIt’s wasn’t something you thought would happen. Your period is LATE!!! And you were sooooo careful — you didn’t use any contraception because you heard if he didn’t ejaculate or pulled out right away, you couldn’t get pregnant. And, just to be extra sure, you did jumping jacks for several minutes right after! What went wrong? Is it possible that the information you heard from your friends about how not to get pregnant was incorrect?


Sperm have one mission: to find and fertilize an egg. They don’t care what position you’re in, whether you have an orgasm, or if it’s your first time.


You know how babies are made, but you may have misunderstood some basic facts of human biology. The male body produces that tiny resilient sperm — actually millions of tiny resilient sperm — whose only mission is to find and fertilize a woman’s egg. They are so resilient that they can travel farther and live longer than you might think. They are present in men’s ejaculated fluid (semen) and also in the pre-ejaculate (the small amount of fluid that leaks out of the penis before a guy ejaculates). If any of that semen comes in contact with a woman’s vaginal area, there is a chance of her becoming pregnant. And if you don’t use some form of contraception with each and every act of intercourse, you are having unprotected sex, which increases your risk of getting pregnant. It only takes one sperm to fertilize an egg.

Let’s look at some common misconceptions you may have heard about how not to get pregnant. Continue reading

STD Awareness: 10 Myths About Sexually Transmitted Diseases

The Internet is brimming with contradictory claims about sexual health, and you don’t know what to believe. Your friends give you advice, but you’re not sure if it sounds right. To make things worse, you might not have had evidence-based, medically accurate sex education in your school. In this edition of our STD Awareness series, we’ll take on a few myths about sexually transmitted diseases to help you sort fact from fiction.

1 MYTH: You can tell if someone has an STD by looking at them.
You might expect that if someone has an STD, their genitals would have blisters, warts, or noticeable discharge. But your partner looks fine, so you might think there’s no need to ask when his or her last STD test was.

However, while many people with STDs do have visible symptoms, they’re the exception rather than the rule. For example, three out of four women and half of men with chlamydia have no symptoms. Herpes is often spread when there are no symptoms present. Someone can be infected with HIV — and capable of transmitting it to others — and go years without showing any signs. A quick visual inspection can’t tell you very much about someone’s STD status.

2 MYTH: You can’t get an STD from oral sex.
While it is generally true that oral sex presents less of a risk for contracting STDs, this risk is not trivial. Most STDs can be passed along by oral sex, including chlamydia, gonorrhea, syphilis, hepatitis B, herpes, human papillomavirus (HPV), and HIV. You can reduce your risk by using barrier methods like condoms and dental dams consistently and correctly.

3 MYTH: Condoms can’t prevent the spread of HIV.
Many proponents of abstinence-only education state that condoms don’t protect against HIV, claiming that latex condoms have holes that are large enough for viruses to pass through. This claim isn’t backed by evidence. An intact latex condom dramatically reduces your risk of being exposed to sexually transmitted viruses such as HIV. (It is true that a lambskin condom does not provide adequate protection against HIV.) Continue reading
