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.
PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
In Japan, records (including detailed shunga) show that some males engaged in penetrative anal intercourse with males, and evidence suggestive of widespread male-female anal intercourse in a pre-modern culture can be found in the erotic vases, or stirrup-spout pots, made by the Moche people of Peru; in a survey, of a collection of these pots, it was found that 31 percent of them depicted male-female anal intercourse significantly more than any other sex act. Moche pottery of this type belonged to the world of the dead, which was believed to be a reversal of life. Therefore, the reverse of common practices was often portrayed. The Larco Museum houses an erotic gallery in which this pottery is showcased.
So I withdraw and push in a well lubed but pretty big thick black vibrating polyurethane offset rotating dildo, which once it’s five inches in I switch on and it’s buzzing gently and (invisibly) twirling around offset inside her anus – and STILL it’s her first time and now she’s bloody mad for it. I get the vibrations and the whirling to maximum – she’s almost babbling with pleasure. All on her first anal date!!
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.”

If done right, absolutely. While it’s true that anal is one of the riskiest types of sex, in terms of spreading sexually transmitted disease – including HIV – if you follow safe sex practices and do it with someone you trust and respect (even better, someone you love), it’s perfectly safe. Go slow, be gentle, listen to each other, use lots of lube, and wear a condom and you’ll be fine.
Maybe you're super excited to try anal and you want to get right in there — don't. It's always best to start slowly with a new sexual experience, but is especially important when you're trying anal sex because the sphincter muscles in an anus are tightly closed. So, instead of jumping in with a penis or sex toy, have your partner stick one (lubed up!) finger inside your rectum first. Then, slowly add more fingers until you're ready to move on to penetration with a penis or with a strap-on.
Pelvic exam : An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.

"I tried it once a long time ago. The guy I was seeing wanted to do it, and I was resistant but eventually gave in. He tried to put it in, but it just hurt too much. I don't think he used lube, and it's just really tight. Maybe I'd do it again with the right person if I had a lot of trust in him. Either way, it's not something at the top of my list." —Clara A.
A small number of anal cancers are known as adenocarcinomas. These start in cells that line the upper part of the anus near the rectum. They can also start in the glands under the anal mucosa that release secretions into the anal canal. Most anal adenocarcinomas are treated the same as rectal carcinomas. For more information, see Colorectal Cancer.
"My guy absolutely loves anal sex from time to time, so any time he does something particularly sweet, brave or helpful for me, I very often reward him with my waiting derriere. Not only does he totally appreciate me offering, but in the B.F. Skinner "operant conditioning" model of psychology, it reinforces him doing sweet, brave and helpful things in the future!" says Singer.

Oral sex and mutual masturbation are more common than anal stimulation among men in sexual relationships with other men. According to Weiten et al., anal intercourse is generally more popular among gay male couples than among heterosexual couples, but "it ranks behind oral sex and mutual masturbation" among both sexual orientations in prevalence. Wellings et al. reported that "the equation of 'homosexual' with 'anal' sex among men is common among lay and health professionals alike" and that "yet an Internet survey of 180,000 MSM across Europe (EMIS, 2011) showed that oral sex was most commonly practised, followed by mutual masturbation, with anal intercourse in third place".
4.“Tight almost to a fault at first then…. nothing. Personally for me it’s just mental, PIV feels much better, like 500% better but sometimes it’s nice just to have that visual and mental that comes with anal. Since it’s a bit uncomfortable for her, i.e I can’t stroke like we do with PIV it’s hard for me to orgasm during anal so if we do it it’s the last 5 minutes or so of a session.”
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?
