Christian texts may sometimes euphemistically refer to anal sex as the peccatum contra naturam (the sin against nature, after Thomas Aquinas) or Sodomitica luxuria (sodomitical lusts, in one of Charlemagne's ordinances), or peccatum illud horribile, inter christianos non nominandum (that horrible sin that among Christians is not to be named).[130][131][132]

Intra-rectal pressure builds as the rectum fills with feces, pushing the feces against the walls of the anal canal. Contractions of abdominal and pelvic floor muscles can create intra-abdominal pressure which further increases intra-rectal pressure. The internal anal sphincter (an involuntary muscle) responds to the pressure by relaxing, thus allowing the feces to enter the canal. The rectum shortens as feces are pushed into the anal canal and peristaltic waves push the feces out of the rectum. Relaxation of the internal and external anal sphincters allows the feces to exit from the anus, finally, as the levator ani muscles pull the anus up over the exiting feces.
That depends on the toy. You want something with a flared base that’s not going to get lost in there, so stick with things marketed for sexy times, not household items that double as sex toys. (It happens.) A toy can be a great warm-up for the main event; you’ll want to use something that’s easy to wash and will stimulate you in the right way. There are so many fun toys on the market – shop around and find the perfect one for you and your partner.
6. Throw other stimulation into the mix. Listen, they don't make those wild-looking, three-pronged sex toys for nothing. Once you're in the groove of things, add in some clit stimulation, some vaginal stimulation, or heck, all three. Some women say this combo feels overstimulating in the best way. In any case, most women need some combination of stimulation to orgasm—whether that's clit/vaginal, or anal/clit+vaginal is totally subjective. But isn't it fun to learn new things about your own orgasms?

One of the biggest trepidations people have about trying anal sex is that "that's where the poop comes from." But that's actually not 100% true, Pitagora says. "Concerns about dirtiness or messiness are not as relevant as you might think because feces are not stored where anal sex happens (near the anus and rectum), but in the upper bowels," they say.
Anal sex has never been a pleasant thought to me…till last night my boyfriend and I decided to try it out. We had a few drinks together and had sex the usual entry whilst that, we were having so much fun that I insisted we try anal and of course like any other guy wouldn’t disagree, we did. WOW! It was amazing! I had 3 orgasms consecutively! Something i have never done before! What better way to enjoy your sex.

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]
Another really common cause is a hemorrhoid (yup, we're talkin' hemorrhoids, folks) you didn't know about. This is a bit more alarming, because a hemorrhoid holds a bunch of blood inside. You'll probably feel some level of discomfort or pain if you have a hemorrhoid, and if it bursts, you'll definitely see some bleeding that should totally subside within a few days.
The development of the anus was an important stage in the evolution of multicellular animals. It appears to have happened at least twice, following different paths in protostomes and deuterostomes. This accompanied or facilitated other important evolutionary developments: the bilaterian body plan, the coelom, and metamerism, in which the body was built of repeated "modules" which could later specialize, such as the heads of most arthropods, which are composed of fused, specialized segments.
One person described it as “like getting a tattoo: It hurts, but you know you still love it.” Another person compared it to popping a painful pimple: “The first few seconds can sting, but the sense of relief and endorphins rush immediately afterwards floods out the momentary ‘pain.’” A few other people compared it to the pain you experience when working out. “It hurts because it’s a muscle being stretched. When you first work out, your muscles hurt because they’re being stretched, but you feel good. Similar good feeling but exponentially better.”
The tissue and skin around the anus acts as a protective barrier for the bottom half of your digestive tract. However, the tissue inside the anus is thinner, delicate, and more likely to tear and bleed as a result of penetration. This increases the likelihood of passing infections, viruses, or bacteria between partners. Even two partners who don’t have any sexually transmitted infections (STIs) can still pass bacteria between each other through these tears in the skin.
