But you can't just slide into anal sex (unless you're using plenty of lube...but more on that later). If you don't know what you're doing and you aren't careful, you could hurt yourself or your partner because the anus is sensitive. "Contrary to what many believe, anal sex does not have to be painful (unless people engaging in it want it to be)," says Dulcinea Pitagora, a sex therapist known as the Kink Doctor. So before you give anal a try, read our tips about how to prep, both physically and mentally.
8. The right lube is twice as important as it is when having vaginal sex, which is already super-important. You might have heard that too much lube takes away the friction that makes it feel good for the dude. That's bullshit. There is no such thing as too much lube, because it makes it feel slightly less like you are using your butthole as a handbag for a flashlight.
The risk of getting HIV varies widely depending on the type of sexual activity. Anal sex (intercourse), which involves inserting the penis into the anus, carries the highest risk of transmitting HIV if either partner is HIV-positive. You can lower your risk for getting and transmitting HIV by using condoms the right way every time you have sex; choosing lower risk sexual activities; taking daily medicine to prevent HIV, called pre-exposure prophylaxis (PrEP); and taking medicines to treat HIV if you have HIV, called antiretroviral therapy (ART).
You may need them to treat an infection, but some can kill the “good" bacteria that live in your bowels. You need those to keep your gut in natural balance, so diarrhea can be a common side effect. You also may be more likely to get a yeast infection while taking antibiotics. Ask your doctor if eating yogurt or taking a probiotic supplement may help.
"I used to be obsessed with anal. At one point in high school, I was having more anal than regular sex. When done right—and by right I mean when the guy doesn't shove his d*ck into you like a horse in heat—anal can teeter on that dangerous line between pleasure and pain. He feels bigger than ever and completely fills you up. As he's going in, you have to hold your breath because you feel like your body doesn't have room for air and his d*ck at the same time, but once he's in, the pleasure radiates through your whole body." —Nina T.
It can be scary when you're trying something new, especially when it involves a body part you're not use to anyone touching. But try to relax as much as possible, because it will make anal sex better, Pitagora says. "Anoreceptive sex is enhanced by an openness to the experience, trust of the insertive partner, an associated sense of arousal, and the ability to overcome the stereotypical taboo," they once wrote in a paper. Bottom line, do whatever it takes to feel as comfortable as possible, because when you're relaxed you'll enjoy the experience more.
“The truth is that our minds have this incredible way of making things less enjoyable for us, if it’s something that we’re not totally into,” Levkoff says. “If we’re nervous or uncomfortable our body shows it — our muscles tighten, we start to clench, we feel anxious, we’re not relaxed and ready anymore, and that means we’re less likely to feel pleasure.”

Male-male anal sex was not a universally accepted practice in Ancient Greece; it was the target of jokes in some Athenian comedies.[106] Aristophanes, for instance, mockingly alludes to the practice, claiming, "Most citizens are europroktoi (wide-arsed) now."[107] The terms kinaidos, europroktoi, and katapygon were used by Greek residents to categorize men who chronically[108] practiced passive anal intercourse.[109] While pedagogic pederasty was an essential element in the education of male youths, these relationships, at least in Athens and Sparta, were expected to steer clear of penetrative sex of any kind. Greek artwork of sexual interaction between men and boys usually depicted fondling or intercrural sex, which was not condemned for violating or feminizing boys,[110] while male-male anal intercourse was usually depicted between males of the same age-group.[111] Intercrural sex was not considered penetrative and two males engaging in it was considered a "clean" act.[106] Some sources explicitly state that anal sex between men and boys was criticized as shameful and seen as a form of hubris.[110][112] Evidence suggests, however, that the younger partner in pederastic relationships (i.e., the eromenos) did engage in receptive anal intercourse so long as no one accused him of being 'feminine'.[113]
27.“From a straight guy’s perspective: Like a lot of the previous comments, there’s an element of the taboo involved in it. Anal isn’t quite as accepted in ‘mainstream’ sexual discussions yet, and as such remains a bit out of reach for many curious individuals. Having already done anal on occasion with my girlfriend, the taboo is still there but has been transferred from a ‘mysterious and unknown’ sort of taboo to a ‘so rare as to be mystical’ taboo. On the pleasure side of things, it provides a nice change in sensation from vaginal, oral, and manual stimulation. And while it may not provide as much physical pleasure, its infrequency offsets that since it’s not something you’re typically used to like one of the above three. Also, the intimacy factor can’t be overstated. Because it’s such a rare occurrence for most guys (myself included), it carries a lot of weight when your girlfriend/wife/FWB/etc. gives you the opportunity. It requires more trust and communication than regular sex, and oftentimes your SO is sacrificing some of their comfort (and possibly dignity) to give you pleasure. It’s honestly both thrilling and humbling.”

Unlike vaginas, buttholes don't produce their own lubrication — so you have to help them along. Pitagora suggests using a water-based lubricant like K-Y Jelly or Astroglide. If you're not using silicone sex toys, you can also use a silicone-based lubricant, which tends to be more slick and lasts longer. But, if you're using condoms, avoid oil-based lubricants (like Vaseline) because they can damage the condom.
Sometimes women are turned off by the hygienic and health aspects of anything going on in the backdoor. "Many women express concern about this as an issue, but as long as you poop and then everything is cleaned out prior with an enema beforehand, there is very little chance of catching anything in there! I prefer natural enemas with no scent as these tend to irritate the rectum which can lead to a painful experience," says Singer.
Research indicates that anal sex occurs significantly less frequently than other sexual behaviors,[1] but its association with dominance and submission, as well as taboo, makes it an appealing stimulus to people of all sexual orientations.[5][18][19] In addition to sexual penetration by the penis, people may use sex toys such as butt plugs or anal beads, engage in fingering, anilingus, pegging, anal masturbation or fisting for anal sexual activity, and different sex positions may also be included.[5][20] Fisting is the least practiced of the activities,[21] partly because it is uncommon that people can relax enough to accommodate an object as big as a fist being inserted into the anus.[5]
Anal sex is a type of sexual intimacy that people have always explored, but advice about how to do it and how to enjoy it are often lacking — especially when compared to advice about vaginal sex and oral sex. So BuzzFeed Health spoke with the following sex educators and sex therapists for the comprehensive anal sex education that was probably missing from your life:

There is less research on anal sexual activity among women who have sex with women compared to couples of other sexual orientations. In 1987, a non-scientific study (Munson) was conducted of more than 100 members of a lesbian social organization in Colorado. When asked what techniques they used in their last ten sexual encounters, lesbians in their 30s were twice as likely as other age groups to engage in anal stimulation (with a finger or dildo).[2] A 2014 study of partnered lesbian women in Canada and the U.S. found that 7% engaged in anal stimulation or penetration at least once a week; about 10% did so monthly and 70% did not at all.[70] Anilingus is also less often practiced among female same-sex couples.[71][72]

Signs and symptoms of STDs in men Sexually transmitted diseases (STDs), or sexually transmitted infections (STIs), can affect anyone, but some symptoms are different for men and women. In this article, we look at the signs and symptoms of common STIs in men and when they typically occur. We also discuss how to diagnose, prevent, and treat STIs in men. Read now
Some infections can cause problems during pregnancy, such as Giardia (giardiasis) and Group B Streptococcus (GBS), among others. Giardia can cause chronic diarrhea which may lead to dehydration and malnutrition, both of which can be dangerous during pregnancy both for the mother and fetus. GBS may be transmitted to the baby during delivery and can lead to an infection in the infant. Both Giardia and GBS often colonize the rectum and can be spread to the vaginal tract if vaginal or oral sex follows anal sex, or if there is any touching (hands or genitals) after anal sex.
Even though serious injury from anal sex is not common, it can occur. Bleeding after anal sex could be due to a hemorrhoid or tear, or something more serious such as a perforation (hole) in the colon. This is a dangerous problem that requires immediate medical attention. Treatment involves a hospital stay, surgery, and antibiotics to prevent infection.
Most of the risk with oral sex is associated with the possibility of contracting or spreading STDs. Almost all STDs can be spread through oral sex, like HIV, the virus that causes AIDS. Herpes (mostly HSV-1), gonorrhea, and chlamydia can all infect the mouth, lips, or throat. If you have herpes type 1 (cold sores) and perform oral sex, you may transmit it to your partner which could cause genital herpes to develop.
14. Like peeing immediately after sex to avoid a UTI, it's good to go to the bathroom right after you're done. You'll also probably feel like you have to anyway. You have also opened yourself up to the joy of butt queefs. They're not farts, no matter what anyone says. Unlike frontal queefs, they might go on for a few hours as the air escapes. On the bright side, you are a human beatbox, and your partner can lay a sick freestyle over the top if s/he feels so inclined.
