Our happy hour fact to amaze your drinking buddies with.

According to a new national study, "experimental" sex is more prevalent among Americans today than it was in 1994.

The Center for Sexual Health Promotion at Indiana University surveyed 5,865 people between age 14 and 94 on their sexual activities. The questions used were similar to a 1994 sex study conducted by The University of Chicago. Compared to the figures from the 1994 survey, it was discovered that more men and women are engaging in oral sex with each other, and a "significantly greater" amount of heterosexual anal sex is going on in 2010. These days, 40 percent of women between the ages of 20 and 45 have engaged in anal sex.

Also notable: The Indiana researchers found 41 different ways people have sex with each other. They also reveal that 85 percent of men claim they gave their partner an orgasm during their latest sexual event, whereas only 64 percent of women said they achieved orgasm during their most recent sexual encounter.

The discrepancy in that last factoid is why findings on self-reported sex surveys need to be digested with a bit of skepticism.
