A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
"I used to be obsessed with anal. At one point in high school, I was having more anal than regular sex. When done right—and by right I mean when the guy doesn't shove his d*ck into you like a horse in heat—anal can teeter on that dangerous line between pleasure and pain. He feels bigger than ever and completely fills you up. As he's going in, you have to hold your breath because you feel like your body doesn't have room for air and his d*ck at the same time, but once he's in, the pleasure radiates through your whole body." —Nina T.

Of course, it is possible that you might encounter a little poop, especially if the receiving partner hasn't had a bowel movement recently (and so, fecal matter may have moved lower in your colon) or if there's residue from a previous bowel movement. Maybe a little poop isn't a big deal to you or your partner — that's great! But if it is, you can take steps to make sure there's no fecal residue left before you get started. "Most people don't regularly have much residue in their rectum, but when they do, the issue can be rectified (pun intended) by anal douching or washing prior to anal sex," Pitagora says.

Anal warts (also called condylomas) are growths that form just outside the anus and in the lower anal canal below the dentate line. Sometimes they can be found just above the dentate line. They're caused by infection with human papilloma virus (HPV). People who have or had anal warts are more likely to get anal cancer. (See “Potentially pre-cancerous anal conditions” below and Risk Factors for Anal cancer)
Unlike vaginas, buttholes don't produce their own lubrication — so you have to help them along. Pitagora suggests using a water-based lubricant like K-Y Jelly or Astroglide. If you're not using silicone sex toys, you can also use a silicone-based lubricant, which tends to be more slick and lasts longer. But, if you're using condoms, avoid oil-based lubricants (like Vaseline) because they can damage the condom.
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.
Oral sex is generally only deemed “likely safe” during pregnancy if you are in a mutually monogamous relationship in which both of you have tested negative for STDs. For those who choose a new sexual partner or have multiple sexual partners during pregnancy, there is the risk of contracting STDs, of which many can negatively affect a pregnancy and the developing fetus.
9. This is a case where shower or bathtub sex might actually be good. Usually, shower sex is bad and very hard to successfully pull off. But because relaxation is so key here, trying anal play in a place where you're more likely to feel calm and loose is helpful. Plus, if you're worried about cleanliness (which isn't a real problem, but it's an understandable concern), moving things to a place where you're already getting clean helps out.

Many men find anal intercourse more exciting than penile-vaginal intercourse because the anal opening is usually smaller and tighter than the vagina. Probably the forbidden aspect of anal intercourse also makes it more exciting for some people.
Because most research on anal intercourse addresses men who have sex with men, little data exists on the prevalence of anal intercourse among heterosexual couples.[6][49] In Kimberly R. McBride's 2010 clinical review on heterosexual anal intercourse and other forms of anal sexual activity, it is suggested that changing norms may affect the frequency of heterosexual anal sex. McBride and her colleagues investigated the prevalence of non-intercourse anal sex behaviors among a sample of men (n=1,299) and women (n=1,919) compared to anal intercourse experience and found that 51% of men and 43% of women had participated in at least one act of oral–anal sex, manual–anal sex, or anal sex toy use.[6] The report states the majority of men (n=631) and women (n=856) who reported heterosexual anal intercourse in the past 12 months were in exclusive, monogamous relationships: 69% and 73%, respectively.[6] The review added that because "relatively little attention [is] given to anal intercourse and other anal sexual behaviors between heterosexual partners", this means that it is "quite rare" to have research "that specifically differentiates the anus as a sexual organ or addresses anal sexual function or dysfunction as legitimate topics. As a result, we do not know the extent to which anal intercourse differs qualitatively from coitus."[6]
The emotional overture I feel before boarding a roller coaster is about the same as I feel right before embarking on anal sex: excitement, followed by mild hesitation and nervousness. But! The thing about every single roller roaster ride I've been on (so far) is that I've loved them all. No matter how many butterflies are tap-dancing on the bottom of my stomach as the ride lurches up a steep hill, the thrill I feel at the end of the ride is always worth it.
