Our happy hour fact to amaze your drinking buddies with.

Adults dream of sexual activity approximately 8 percent of the time that they sleep.

Researchers at the University of Montreal came to this number after analyzing 3,500 dream dairies collected from both sexes. Men and women reported salacious dreams at about the same rate. (In studies from past generations, women were less likely to report sex dreams; the researchers weren't sure if this is because women are having more sex dreams, or if they have become more comfortable admitting to them.)

However, there are still key differences between the male and female nocturnal subconscious. For example, in 4 percent of feminine sex dreams, her partner achieves orgasm; yet there wasn't a single reported case of a male sex dream in which the woman also gets off.

So if guys aren't even hitting the spot in their dreams, it is certainly advisable that a gal invests in the type of device that can.
