I’ll preface this by saying that I have not seen the actual study, so I can only base my opinions off of the little information given in the article.

In a nutshell, it seems like they just asked a bunch of twins (fraternal and identical), “Do you have a g-spot?”   This is horrible research methodology.  It’s like going to 1920s households and asking the women if they’ve ever experienced an orgasm.   “A significant number of women said that they had never experienced orgasm, therefore we conclude that the female orgasm does not actually exist.”

If you’re serious about this, how about you start by doing some research on female cadavers?   Map out nerve endings, that sort of thing.

To play my own devil’s advocate, I see the point of this study.   I get the impression that the people behind this study believe that many women don’t receive pleasure in that way, and feel like there must be something wrong with them.   Personally I think in most cases that’s most likely because their partner doesn’t know how to properly stimulate it, but that’s neither here nor there.  The study is meant to say, “There, there. It’s okay.  No pressure.” (Pun intended.)  But if you want to say that, then just say it. Don’t try to prove it with bogus science.
