Only a select type will open the back door.
What's even more fascinating is that there are actually specific types of women who are more willing to open the back door than others.
In a study that analyzed data from the National Survey of Family Growth, "10,463 straight, sexually active women between the ages of 15 and 44" were asked if they ever tried anal sex at least once. Researchers found that "36.3 percent of the women surveyed said they've tried anal sex a least once in their lives."
However, it didn't seem like their go-to sex position because "only 13.2 percent said they had anal within the last 12 months."
But there was a trend in the types of women who were trying anal sex: "Women in their twenties who had no religious affiliation, and higher levels of income and education were the most likely to try anal," the study found.
Being in a long term relationship wasn't the only lifestyle pattern that researchers saw. Women were more likely to have anal sex if they've "had sex with women, had an unintentional pregnancy, lost her virginity before the age of 16, and had been treated for a sexually transmitted infection in the past year."
Women who were "wifed up" and unreligious did prove to be more likely to try anal then women in any other circumstance. The study also showed that "women were significantly less likely to use condoms for anal sex than vaginal sex, putting them at a greater risk for contracting an STI."
Yes, anal sex will decrease your chances of getting pregnant. Yes, it's great to keep trying new tricks in the bedroom. However, there's always the risk of contracting an STI both anally and vaginally, so be prepared and do some research before giving anal sex a go.
