Dental Dams Help Spread Intimacy, Not STDs

Posted on by

It’s that time of the year when people focus on intimacy and romance. Most people think jewelry and roses are good gifts to give for Valentine’s Day. They’re nice, but you know what’s even better? Dental dams.

What’s a dental dam, you ask? Like condoms, dental dams are a way to prevent the spread of sexually transmitted diseases (STDs) by covering the vagina or anus during oral sex. Dental dams are usually made of latex, and some are made from polyurethane. Since they’re used for oral sex, dental dams often come in different flavors, and they’re flexible enough to fit in your purse.

Dental dams are an essential component of protecting your sexual health.

Dental dams are particularly useful for lesbian partners, since oral sex is a common form of sexual activity, but anyone who engages in cunnilingus (the oral stimulation of female genitals) can use them. Dental dams are also beneficial for consenting partners who enjoy anal play (aka “rimming”). Dental dams serve as a barrier against most STDs, since many sexually transmitted diseases, such as syphilis, human papillomavirus (HPV), and herpes, can be passed simply by skin-to-skin contact. Gonorrhea, chlamydia, and hepatitis A and B viruses can also be spread through oral sex. HIV can be transmitted through oral sex if blood is present.

Unfortunately, dental dams aren’t distributed as widely as condoms are. You’re not likely to find a dental dam dispenser in a public restroom, and many community organizations provide dental dams on a request-only basis because they’re more expensive than condoms. And most drug stores don’t carry dental dams in the same aisle as condoms and lube because dental dams were originally created to be used during dental procedures. (Get it — dental dams.)

STD Awareness: Can I Use Plastic Wrap as a Dental Dam During Oral Sex?

Posted on by

plastic wrapIf you read this blog — or any sexual health website, really — you’ll probably see dental dams getting a lot of props. A dental dam (not to be confused with a female condom) is a square piece of latex that can cover the vaginal opening or the anus. Anyone wishing to avoid the oral transmission of STDs like herpes, gonorrhea, HPV, syphilis, chlamydia, and intestinal parasites, dental-dam advocates say, should use a latex barrier. Most people, however, have probably never even seen a dental dam, and they are not widely used. Perhaps their unpopularity is related to myths about oral sex being safe sex (it’s not!); perhaps it’s due to dental dams being expensive or difficult to find.

Plastic wrap hasn’t been evaluated by the FDA for STD prevention, and no studies have assessed its effectiveness in reducing disease risk during oral sex.

Some safer-sex aficionados have found ways around that, though. They might cut the tips off of condoms and make incisions along the sides, creating little latex rectangles. An even easier and cheaper option lies in plastic wrap, which many people use as a barrier while performing cunnilingus (oral contact with the female genitalia) or rimming (oral contact with the anus). It is inexpensive, easy to find, odorless, and tasteless, and can be purchased without even a hint of embarrassment (unless perhaps your other purchases include duct tape, cucumbers, and clothes pins). And it can be pulled off the roll in sheets as long as your heart desires!

Planned Parenthood endorses the use of plastic wrap for oral sex when dental dams aren’t available. The Centers for Disease Control and Prevention and AIDS.gov both recommend plastic wrap for use during rimming. Health authorities, such as AIDS.gov and the Idaho Department of Health & Welfare, recommend non-microwavable Saran Wrap, because microwave-safe Saran Wrap has tiny pores to let out steam — which might also let viruses and bacteria through.

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).

STD Awareness: Can Lesbians Get STDs?

Posted on by

couple WSWA couple of months ago, in time for Valentine’s Day, the Centers for Disease Control and Prevention announced that it would start using the term “condomless sex” instead of “unprotected sex.” The move was hailed by many HIV advocacy groups for taking into account other risk-reduction practices, such as medications that decrease the chances of HIV transmission.

Women can transmit just about any STD to one another.

However, while medications can reduce HIV risk, condoms still offer protection from both pregnancy and many other sexually transmitted diseases (STDs), such as chlamydia and gonorrhea. One reason that condoms are so valuable is that they can be placed over a penis to collect fluids before and after ejaculation — dramatically reducing risk for both pregnancy and many STDs. So, even when using anti-HIV meds, engaging in “condomless sex” can still be risky.

But what if partners are engaged in sexual activities that don’t involve penises? Not all sexual couplings involve a cisgender man, and even those that do might not utilize a penis at every encounter. When two people without penises have sex, they’re probably going to be engaging in condomless sex — though condoms can be placed over penetrative sex toys or cut along the sides to be converted into dental dams, they might not figure too prominently in this couple’s safer-sex arsenal. Lesbians protecting themselves with dental dams are technically engaged in “condomless sex,” but it’s still a far cry from being “unprotected.” Continue reading →

Can Oral Herpes Be Spread to Genitals?

Herpes simplex virus is mystifying, fascinating, and sneaky. Mystifying because we have yet to unravel all of its secrets; fascinating because when we do uncover one of its mysteries, we are amazed by the capabilities of such a tiny, microscopic object; and sneaky because it enters our bodies by stealth and conceals itself in our cells, taking us by surprise when it comes out of hiding and causes outbreaks of blisters and other lesions.

It can also be confusing. Herpes simplex virus actually comes in two flavors: HSV-1 and HSV-2. HSV-1 is associated more with oral herpes, which can cause “cold sores,” a type of blister that appears on the lips or face. HSV-2 is associated more with genital herpes, which can cause blisters and other lesions in the genital area. It used to be standard to describe HSV-1 as an “above-the-waist” infection and HSV-2 as a “below-the-belt” infection — but now many researchers are pointing out that it’s more appropriate to say that HSV-1 is both an orally and genitally transmitted infection while HSV-2 is a predominantly genitally transmitted infection. If HSV-1 enters the body in the genital area, it can cause a genital herpes infection — and likewise, if HSV-2 enters the body in the facial area, it can cause an oral herpes infection.

Using condoms and dental dams during oral sex reduces risk of herpes transmission.

What exactly is a cold sore, anyway? A cold sore, also known as a fever blister, is a cluster of blisters that can pop up around the lips or even in the mouth. Sometimes, cold sores are so painful that eating or drinking is difficult, and in extreme cases sufferers must be treated for dehydration. An especially severe infection could also cause high fever or swollen lymph nodes, and in young adults a first oral HSV-1 infection might be misdiagnosed as tonsillitis, possibly leading to unnecessary tonsillectomies. Most symptomatic first-time cold-sore outbreaks occur during childhood, and take about two or three weeks to clear up. Luckily, the first infection is almost always the most severe, and when the infection is reactivated it usually happens without symptoms.

Because both cold sores and genital herpes are caused by herpes simplex viruses, and because oral herpes is so common, many people are concerned that they might be more vulnerable to acquiring a genital herpes infection than they previously thought. They might have a lot of questions, and if they’ve sought answers to those questions, they might have heard a lot of conflicting answers. Let’s see what the scientific literature has to say.

  • Can I get genital herpes if someone with cold sores performs oral sex on me?

Because HSV-1, the virus responsible for most oral herpes infections, can also cause genital herpes, many people wonder if someone with cold sores can transmit the virus to someone else by performing oral sex, resulting in a genital herpes infection. Other people wonder if HSV-1 can be transmitted via oral contact with the anus, resulting in a herpes infection in the rectal area. The answer to these questions is: Yes! Continue reading →

STD Awareness: 10 Myths About Sexually Transmitted Diseases

Posted on by

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 →

STD Awareness: 10 Sexually Transmitted Diseases You Probably Don’t Know About

Gonorrhea and chlamydia go back to antiquity. Syphilis took hold in Europe during the late 15th century. Herpes wasn’t on most people’s radars until the early 1980s, and human papillomavirus (HPV) was relegated to relative obscurity in the popular imagination until the HPV vaccines made their debuts less than a decade ago.

Have you heard of CMV, chancroid, or donovanosis?

But there are still a handful of sexually transmitted diseases (STDs) that you might not know about. These include incredibly common infections, as well as those caused by pathogens you might have heard of but probably don’t associate with sexual transmission. They also include infections that are very rare here in Arizona but are much more common in other parts of the world. They all deserve a closer look.

10 Trichomoniasis: What is the most common curable STD? You might guess that it’s chlamydia or gonorrhea, but according to the Centers for Disease Control and Prevention, it’s trichomoniasis (also known as trich, pronounced “trick”). This infection is caused by Trichomonas vaginalis, a single-celled parasite that is actually pretty cute as far as microbes go. What’s not so cute is its propensity to attach to your cells and degrade their surfaces, which on a large scale can produce unpleasant symptoms. Continue reading →
