It's taboo, it's deviant, it's outside the norm – we're talking anal sex. But it's also a type of sex that many couples do enjoy, regardless of their sexual orientation. In fact, the Centers for Disease Control and Prevention reported in early 2012 that more heterosexual men and women – 44 percent and 36 percent, respectively – had had anal sex than originally assumed. There are nerve endings in the anus that can make anal play or anal sex pleasurable for both men and women. The shared wall between the prostate in men and vaginal wall for women can give participants pleasure. Biologically speaking, it seems strange to insert something into an orifice that's considered an exit only, but that taboo seems to be part of the appeal for participants. If you and your partner want to give it a try, the key is to take it very, very slow. The supplies you'll need are lots of lubrication – no petroleum jelly – condoms, and perhaps a towel. The receptive partner – that's the one who will be penetrated – shouldn't worry too much about what might come out of the anus during or after the act, but having a bowel movement about an hour or so before anal sex can make things a lot less messy. Washing up helps as well, but anal douching or enemas are not necessarily recommended because they can cause tiny fissures in the anal wall. Being as relaxed as possible is of utmost importance – trusting your partner is the name of the game, and it helps to be aroused before attempting anal sex. Begin with a finger and lots of lube. The sphincter is a muscle that should be stretched a little, just like any other muscle. When and if you're ready, a male partner should always use a condom, regardless of whether or not you're monogamous. Not only do you get the added benefit of lubrication, but it also protects the man from disease and keeps the woman from getting sick as well. Remember to relax as much as possible and use lubrication liberally to have a successful session.
