My aunt inadvertently pointed out this article to me today and I immediately headed over to read up! I learned a new word from the article too, clitourethrovaginal (CUV) complex. Now that's a mouthful (no pun intended!)! The gist of the article is that there is no one specific G-spot but rather we women are a complex system that varies with our hormones and each individual is different. What works for one may or may not work for another.
I also want to point out that the brain plays a huge role for many women and sometimes that is good and sometimes not so good. As someone who reads lots of erotica I can say there are certain descriptions that are treated as gospel for obtaining the female O and the G-spot is certainly part of that. As more research is completed, I hope authors will expand their ideas on the female O as well.
