I learned an interesting stat last night: According to The Kinsey Institute, 85% of men have masturbated with another person in the room, while 66% of women have done the same. The sex educator who told me this said the numbers were higher than previously  thought, and could be higher still due to self-reporting.

What do you think? Are you surprised by these stats?
