So, why do you think blow jobs happen?
This is not a trick question.
Most of us would probably go for the, "Hey, that feels nice," theory of oral sex. But researchers Min Tan, Gareth Jones, Guangjian Zhu, et. al., think there may be more to it than simple pleasure. As part of their attempt to prove a practical function for oral sex, the team conducted a study of the fellatio habits of fruit bats. The paper was published October 28 in the journal PLoS ONE. You can read the whole thing online.
The basic idea here is that there might be some benefit to blow jobs (beyond the obvious) and the fact that bats who engage in fellatio have longer sessions of sex than bats who don't could be evidence in favor of that theory. Why? Because it's showing that oral sex is correlated with a change in behavior and, the scientists theorize, there may be reasons why that behavioral change is beneficial to the animals. How beneficial? The team theorizes that oral sex could be doing everything from increasing the chances of sperm fertilizing egg, to killing bacteria on the penis and protecting both parties from sexually transmitted disease. Of course, the only thing proven is that oral sex means longer sex in fruit bats. The team concedes a need for further research...
