It's important that we talk about all kinds of sex because not everyone is having, or wants to have, "penis in the vagina" sex. If you do have "penis in the vagina" sex and are curious about something else, or are finding that that type of sex is not for you and you'd just like to explore other options, it's helpful to know the facts. Even if you do learn more and decide anal sex is not a thing you'd like to try, it doesn't hurt to have the information.
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]

Strong views are often expressed about anal sex. It is controversial in various cultures, especially with regard to religious prohibitions. This is commonly due to prohibitions against anal sex among males or teachings about the procreative purpose of sexual activity.[5][7] It may be considered taboo or unnatural, and is a criminal offense in some countries, punishable by corporal or capital punishment.[5][7] By contrast, people also see anal sex as a natural and valid form of sexual activity that may be as fulfilling as other desired sexual expressions, and as an enhancing or primary element of their sex lives.[5][7]
Relaxation is key and also making sure you're lubed up. "Like first timers, I mean really wet and slippery trust me sometimes that's the number one problem! The best sex position I've ever felt it in was laying on my stomach and he sneaked it in between my cheeks, laid down on top of me and rubbed my clit with one hand while supporting himself with the other, and whispering dirty things in my ear while nibbling on it," says Jillian Janson, an award-winning adult star.
Chlamydia and erectile dysfunction: What's the link? Some people who have chlamydia also experience erectile dysfunction (ED), which involves problems getting or maintaining an erection. Chlamydia can infect the prostate gland, leading to prostatitis, pain, and ED. In this article, learn more about the link between this common infection and ED, and treatments for both. Read now
Ok, just hear me out… because I don’t want anyone thinking this is 100% birth control. No, your rectum does not connect you anything to cause pregnancy. Think about it like masturbating onto your partner’s vulva (the lips and stuff on the outside), this is because there is a SMALL chance that the little swimmers could swim all the way home. This is not very common, but it is possible.

I admit, I’m sure I missed something in my quick list there. Sure it is POSSIBLE that you could go to the local pool and swim in the water with a woman who just had unprotected anal sex and YOU (if you’re female) end up pregnant from it or there is a chance of either sex catching a disease… but let’s get real, what are the odds in that actually happening??? Sex is risky, it has been since before Christ was born. Refresh my memory, what is the “oldest profession”??? Ever since there were more than just Adam and Eve around, there has been a risk of catching a STD. (The new term STI was probable between just the two of them. Even with conventional sex, being safe, etc… it isn’t uncommon to get a UTI, yeast Infection, etc.. after having sex for several hours with a partner who you have been in a mutually monogamous relationship with for years.) {Note, that was not a religious comment… it was more sarcasm for those who don’t understand what BC actually means.}

In a 2010 clinical review article of heterosexual anal sex, anal intercourse is used to specifically denote penile-anal penetration, and anal sex is used to denote any form of anal sexual activity. The review suggests that anal sex is exotic among the sexual practices of some heterosexuals and that "for a certain number of heterosexuals, anal intercourse is pleasurable, exciting, and perhaps considered more intimate than vaginal sex".[6]
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...
The oil-based ones are also pretty annoying to get off afterwards. We used Vaseline, but my boyfriend later realized that it deadens sensation on the skin, which was obviously helpful for my asshole but bad for his orgasm. So maybe don't do that, or start with a bit of that but then switch, because it'll take really long for your partner to come, if they even can.
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).

It’s a cardinal rule of sex to never go from anal to vaginal penetration without changing the condom (even if the penetration is with a sex toy). This is because introducing fecal matter into a woman’s vagina – even if it’s her own fecal matter – places her at significant risk for developing a urinary tract infection. Women are at higher risk of getting these infections than men because a woman’s “plumbing” is such that her urethra is quite short, making it very easy for bacteria to climb up the urethra and set up camp in the bladder. In some cases, a bad urinary tract infection can even travel from the bladder to the kidneys, which is very serious.
Most anal cancers are cured with combination therapy. If caught early, many cancers that come back after nonsurgical treatment are treated effectively with surgery. While combination radiation/chemotherapy produces more side effects, this approach also results in the best long-term survival rates. After completing this treatment, as many as 70-90% of patients are still alive and cancer free at 5 years.
Brace yourself for the most intense anal sex experience ever. Thousands of busty babes are about to make your wildest fantasies come to life. Bubble butt ladies who love to get really dirty in the bedroom want their asses fingered and fucked all day long. Innocent girls next door hooking up with random guys and taking their big fat cocks inside those sexy asses.
Please explain the risk if you follow ALL safety measures (off the top of my head here are just a few of them to consider): Condom, lots of lube to help prevent condom breakage (and most women I know don’t like dry anal), go slow until things are “ready”, used a toy to stretch things a little bit first, both partners got tested, did your best not to “contaminate” the vagina, were on birth control (in case the condom broke & it was that time of the month & the sperm spread to the vagina), immediately cleaned up, both washed hands immediately and took showers immediately afterwards, cleaned the sheets properly, etc… So if you do all of that, what “very risky” issues are we talking about???
Stretching her asshole open, priming the pump with plenty of lube and watch her lean back as her ass cheeks spread apart and that tight butt-hole begins to gape. Her ass is practically begging you to bone it when you finally enter her from behind and begin building up momentum - thrust after thrust she moans and groans as you get the friction on. That is what makes Anal Sex so much better than simple missionary style fucking. The exotic nature of rear entry and the fact that she is willing to let you enter her anus in the deep ways that others have been denied. Full access fucking and free porn videos are the best combination of erotic elements since spit and sex were first integrated in bedrooms around the world.

During filming, they take cut breaks to apply lube, rarely shown on screen, address messes, and switch from anal back to vaginal sex without showing pre-switch cleaning, which is vital to avoid infections. They also, says self-described “aspiring anal queen” Della Dane, who entered porn last year, “do certain angles and positions for entertainment value that you wouldn’t normally do.” And rather than being ready for anal at any time, stars often need to take breaks of a few days or weeks between a given number of anal shoots. All-in-all, the eight-year industry vet Cherie DeVille told me last year, “you can’t expect your female partner at home to just be able to jump into” anal, especially porn-style anal; the same applies to men and non-binary folks as well.
Although few cancers are totally preventable, avoiding risk factors and getting regular checkups are important. Using condoms may reduce, but not get rid of the risk of HPV infection. HPV vaccines (for those ages 9 to 26) have been shown to not only lower the risk of HPV infection, but also reduce the risk of anal cancer in men and women. People at increased risk should talk to their physicians about getting an anal cancer screening. During this test, your physician swabs the anal lining, looking at the cells under a microscope for anything unusual. Other forms of screening include looking closely at the area during a surgery, or in the office with a special scope to look in the anal canal. Early identification and treatment of precancerous areas may help prevent anal cancer. 
Your nerve endings are sensitive for a reason. They alert your brain to pain so you can prevent yourself from getting seriously injured, Dr. Chinn says. While numbing creams might make anal penetration feel easier, they don’t make it any easier physically. By numbing your anus, you or your partner could be pushing your body past its point of comfort without even realizing it.
Using protection during anal sex is important to reduce your risk of catching an STI. For penetrative sex, make sure you use a condom and lots of lube – some people feel safer using extra-thick condoms for anal sex. Dental dams also offer good protection for rimming. Taking pre-exposure prophylaxis (PrEP) is another way to prevent HIV infection, but it may not be available everywhere.
