I was recently involved in a humourous conversation with several people about how many words there are for the male sex organ. We have concluded that there are more words for that part of the human anatomy than any other. The most common are obviously penis, cock, and dick, though not necessarily in that order. If you are out with your girlfriends, and the subject happens to come up, what word are you most likely to use? Does it depend on context or the type of women you are with?
