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.
This seems to be the top reason as to why women say no to anal sex. "Let's face it. Guys that like being pegged enjoy it as it the dildo stimulates their prostate gland and that pleasure overrides most of the pain of entry," says Coleen Singer of Sssh.com, a porn site for women and couples. "Women don't have that benefit and unless totally relaxed and very well lubricated. Personally, if I haven't had anal sex for a while, I'll pop in a medium size butt plug for an hour or so before taking the penis as it relaxes the sphincter and makes penetration much more pleasant," says Singer.

Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include fingering, the use of sex toys for anal penetration, oral sex performed on the anus (anilingus), and pegging. Although anal sex most commonly means penile–anal penetration, sources sometimes use anal intercourse to exclusively denote penile–anal penetration, and anal sex to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation.
The anal sphincter acts as a bit of a gatekeeper for the rectum. For anal sex, however, it’s important that this muscle relaxes. Not only does it make the experience more pleasurable, it reduces the risk of tearing or discomfort. Relaxation involves patience, both at the time you’re attempting penetration, and as you become more accustomed to anal sex.
