As food is digested, it passes from the stomach to the small intestine. It then moves from the small intestine into the main part of the large intestine (called the colon). The colon absorbs water and salt from the digested food. The waste matter that's left after going through the colon is known as feces or stool. Stool is stored in the last part of the large intestine, called the rectum. From there, stool is passed out of the body through the anus as a bowel movement. The anal sphincter (SFINK-ter) muscles control the passing of stool. These are ring-shaped muscles around the anus that keep stool from coming out until they are relaxed during a bowel movement.

Anal sex videos introduce porn lovers to a journey into the netherworld. Often involving the insertion of a dick into an asshole, anal intercourse can also imply fingering or the use of sex toys. Anal penetration can even involve multiple cocks at once. Anal sometimes ends with an internal cumshot, known as a creampie, which can be a sweet surprise!
17. It feels best when there's some additional stimulation going on. Vaginal, clitoral, nipple-centric—whichever feels best for you. While some women only need butt play à la carte, most women can't come from anal stimulation alone. "The anal part is something that's an accent. It adds to the overall experience," says Ian Kerner, sex expert, researcher, and author of She Comes First: The Thinking Man's Guide to Pleasuring a Woman. (Incidentally, women who have had anal sex report more frequent orgasms than those who haven't.) That being said...
If you’re going ver-r-r-y slowly and using lots of lube, but it’s still not happening, don’t fret. There are plenty of other ways to have fun back there; there’s no need to be too hung up on penetration. But who knows? After a little tongue and finger play, you might just be warmed up enough to try again. You can also try an ‘anal easing’ lubricant, designed to gently relax the anal area for easy insertion, like this one:
15. “Personally, I don’t understand some peoples’ obsession, when there’s a perfectly good vagina right next door. Only a few GFs over my long and varied love life were into it, and for them it was like an occasional naughty treat. On these occasions there’s an extra hotness factor added in mentally. As for the raw physical characteristics of tightness and friction, vaginal is better in the long run. I once had a GF who was down for it any time, and we both got bored of it really quickly TBH. On the other hand, a different GF had done some rotten things and we broke up; while making up months later we were in bed spooning naked when suddenly her ass cheeks then asshole started gobbling my cock like Pac-Man, a one-off event that was hotter than molten tungsten.”
Glickman recommends starting with your face looking down at the bed and getting on your elbows and knees, rather than hands and knees, because you want your hips higher than your shoulders, so the penetrator has easier access. He also recommends trying the position where the receiver is standing and bent over the bed, or doing cowgirl/cowboy with the receiver straddling so that they can control the depth and pace.
CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the abdomen or chest, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. For anal cancer, a CT scan of the pelvis and abdomen may be done.

Yes, you can still contract or transmit STDs through anal and oral sex. Anal sex can more easily damage tissue (tears in the lining of the anus or rectum) than during vaginal sex because the anus is not designed for insertion. Therefore, the skin barrier that often protects against infection is broken and STDs can more easily enter the body. This means that transmitting or contracting an STD is more likely from anal sex than with vaginal or oral sex.
Using a new condom is especially important if you’re switching from anal to vaginal penetration so you can avoid moving bacteria from your anus to your vagina or urethra. Your anus is home to all kinds of bacteria your vagina and related parts aren’t used to—namely, gastrointestinal (GI) bacteria, like E. coli. When this bacteria reaches your vagina, it can cause vaginal infections, like bacterial vaginosis, which can lead to vaginal itching, burning during urination, a “fishy” vaginal odor, and gray, white, or green vaginal discharge, according to the Mayo Clinic. It can also spread to your urethra, where it can cause a urinary tract infection. According to the Mayo Clinic, this can cause symptoms like constantly needing to pee, then a burning sensation when you do, along with cloudy urine and pelvic pain.
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.
From Behind – Once you are comfortable with your man having more control and doing all the thrusting, then you may want to try out some doggystyle type positions, where your man is fucking you from behind. I’ve put together an entirely separate guide on the 19 best anal sex positions here where you are in the doggystyle position or a variation of it.
Spreading STIs. Infections and diseases that are shared during sexual intercourse — such as HIV, gonorrhea, chlamydia, and herpes — can be shared through anal sex. In fact, anal sex is the sexual behavior for transmitting and getting HIV for both men and women. People on the receiving end (or “the bottom”) of anal sex are more likely to become infected with HIV than the inserting partner (or “the top”).
