Reduce your risk of cutting or scratching your partner by trimming your nails. Long nails might tear the thin, delicate tissue of the anus, which could lead to bleeding. It also increases the risk of spreading bacteria that could cause infections. Be sure to wash your hands well and scrub under your nails after anal sex, too, especially before inserting them into the vagina or mouth.

In addition to HIV, a person can get other sexually transmitted diseases (STDs) like chlamydia and gonorrhea from anal sex without condoms. Even if a condom is used, some STDs can still be transmitted through skin-to-skin contact (like syphilis or herpes). One can also get hepatitis A, B, and C; parasites like Giardia and intestinal amoebas; and bacteria like Shigella, Salmonella, Campylobacter, and E. coli from anal sex without a condom because they’re transmitted through feces. Getting tested and treated for STDs reduces a person’s chances of getting or transmitting HIV through anal sex. If one has never had hepatitis A or B, there are vaccines to prevent them. A health care provider can make recommendations about vaccines.


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.
There are little published data on how many heterosexual men would like their anus to be sexually stimulated in a heterosexual relationship. Anecdotally, it is a substantial number. What data we do have almost all relate to penetrative sexual acts, and the superficial contact of the anal ring with fingers or the tongue is even less well documented but may be assumed to be a common sexual activity for men of all sexual orientations.[67]
Your man also needs to be someone who will actually follow your instructions too. If he thinks he is going to be in control and calling the shots, then you are going to have to bring him down to earth and let him know that this won’t be the case. Doing this isn’t so that you can “dominate” your man, it’s so that you get to experience the pleasures of anal sex AND NOT THE PAIN.
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
The Renaissance poet Pietro Aretino advocated anal sex in his Sonetti Lussuriosi (Lust Sonnets).[125] While men who engaged in homosexual relationships were generally suspected of engaging in anal sex, many such individuals did not. Among these, in recent times, have been André Gide, who found it repulsive;[126] and Noël Coward, who had a horror of disease, and asserted when young that "I'd never do anything – well the disgusting thing they do – because I know I could get something wrong with me".[127]
Feast your sight on the most amazing redheads spreading their juicy ass cheeks and biting their lips with lust when taking dicks in those tight holes. Gorgeous blondes and insatiable brunettes are about to get anally lubed and fucked for massive orgasms. Massaged debutantes begging for anal sex with strangers and cuckolding wives taking it up the backdoor while their husbands watch.
“I hate to say I'm not a big G-spot believer. There certainly are some nerves, but [research hasn’t] been able to anatomically demonstrate much on a regular basis,” Mary Jane Minkin, M.D., a clinical professor of obstetrics, gynecology, and reproductive sciences at Yale Medical School, tells SELF. “I think women have areas that are more sensitive than others, individual exploration is good, and individuals can experience stimulation in all sorts of places."
3. Once you are both used to it, I find that often her lubrication coming out from vaginal sex and all over my penis when I pull out is all I need for anal penetration. (Tried the first time after 5-6 regular anal encounters.) Just warn her before you switch, or make sure you know her body enough before you try this without a warning. Depending on gravity and how excited she stays, I often find that she stays almost as wet in the back as the front… but she REALLY likes it as she can have multiples “back to back” in either entrance!!! Before we met, she was 35, she had tried anal once and hated it, and had only had 6 orgasms total during intercourse in her life, now she has 6 in a row or more just during the anal part of things.
In animals at least as complex as an earthworm, the embryo forms a dent on one side, the blastopore, which deepens to become the archenteron, the first phase in the growth of the gut. In deuterostomes, the original dent becomes the anus while the gut eventually tunnels through to make another opening, which forms the mouth. The protostomes were so named because it was thought that in their embryos the dent formed the mouth first (proto– meaning "first") and the anus was formed later at the opening made by the other end of the gut. More recent research, however, shows that in protostomes the edges of the dent close up in the middle, leaving openings at the ends which become the mouth and anus.[2]
Colon and rectal surgeons are experts in the surgical and non-surgical treatment of diseases of the colon, rectum and anus. They have completed advanced surgical training in the treatment of these diseases as well as full general surgical training. Board-certified colon and rectal surgeons complete residencies in general surgery and colon and rectal surgery, and pass intensive examinations conducted by the American Board of Surgery and the American Board of Colon and Rectal Surgery. They are well-versed in the treatment of both benign and malignant diseases of the colon, rectum and anus and are able to perform routine screening examinations and surgically treat conditions if indicated to do so.

During pregnancy especially, it is important that if you are receiving oral sex that your partner does not blow into the vaginal opening and cause any air to be trapped inside the vagina. This is because this bubble of air can travel and enter the placenta, which can cause problems with fetal development. Additionally, the pressure differential caused by air being trapped in the vagina can cause blood vessels to rupture, causing spotting or bleeding.
3. If it hurts, stop! Some, well, let's call them new sensations are to be expected—a lot of women say it feels like they need to poop, or like a primal, pressure feeling. But like any other sex act, if things start to hurt in a way that's no longer fun, you should stop. Injuries from anal sex are possible, but super rare. Pain most commonly comes from anal fissures, or little tears in the tissue around the anus, which is very thin and delicate. A good way to remedy that is using lots of lube and smarting with smaller objects, rather than big ones.
