Don't blame yourself or your partner—blame the fact that you may not have one. Anna Pulley writing at Salon:
If you’ve been one of the countless people searching in vain for the elusive Gräfenburg spot (aka the G-spot) or wondering why you aren’t gushing like Old Faithful each time someone makes a “come hither” motion in your vagina, then search and wonder no more. Once lauded as a “magic button” and the ultimate female pleasure enhancer, an Italian scientist’s recent report claims once and for all that the controversial G-spot is nothing but a myth (with a really good PR campaign). The study—published in the journal Nature Reviews Urology by Emmanuele Jannini, Professor of Endocrinology and Medical Sexology at Tor Vergata University of Rome, Italy—found that, essentially, the G-spot is just a sensitive area that’s part of the larger pleasure center that includes the vagina, clitoris, and urethra, or as the study sexily put it, the “clitourethrovaginal (CUV) complex.”
Jannini’s most recent work on the G-spot hype does alleviate some of the sexual pressure faced by both men and women. We can now safely put away our magnifying glasses and ignore the sex advice that would have us attempting sign language in our partner’s vaginas (unless, of course, you enjoy that). While clitourethrovaginal complex is much harder to say and spell than old Ernst’s term, it’s interesting to know that the female pleasure region is not limited to any specific spot, but instead functions as a team that all works together to make your face contort like that. In other words, there may not be an “I” in “team,” but it appears there is an “O.”
I've spoken with a lot of women who swear by that "come hither" motion—and who require precisely that kind of stimulation to get off and/or to squirt—and I find it hard to believe they were all deluded.
Now I haven't dug into the G-spot literature lately but I'm pretty sure no one was arguing that the G-spot was a stand-alone organ, like a bonus kidney or something. So I'm not convinced that placing the G-spot on Team CUV disproves its existence. Couldn't the G-spot (a location, not an organ) be one part of a larger clitourethrovaginal complex with some women deriving more pleasure from its stimulation than others? That some women experience intense pleasure from having this one particular part of their CUV complex stimulated seems no more remarkable to me than the fact that some men derive intense pleasure from having their balls played with or their taints licked. (The balls and taint, of course, are both important parts of the peniurethroballsackinal (PUB) complex.)
