As you may have heard, recent research from King’s College in London has suggested that the G-spot is a myth. According to the report:
The study suggests that there is no genetic basis for the G-spot and that environmental or psychological factors may contribute to whether a woman believes that she has a G-spot. The new study is published in the Journal of Sexual Medicine.
This has been getting a lot of news play (no pun intended), even within traditional news sources like the Clitoral News Network. Since there are far more pressing things going on in the world, I thought this was best left to the always excellent web comic xkcd.

the g-spot being a myth is a myth in itself. (insert reference to your mother/girlfriend/sister here)
