Is there a G-spot or not?

Is there a g-spot? Where is this elusive piece of female anatomy to be found? Can women ejaculate? Periodically this subject rears its head and gets debated, generally when someone spouts off a load of verbiage about how all women have one (it is just they are repressed, haven't found the right partner etc.) and once found can squirt and have wonderful mind-blowing ecstatic orgasms, or that no women have one and this is a myth perpetuated by various nefarious individuals and the porn industry.

The recent splurge of debate and calls for better research (which i agree with, where do I sign up?) stem from a particular Dan Savage podcast (http://itunes.apple.com/us/podcast/savage-love-podcast/id201376301) that was then roundly criticised on Blag Hag (http://www.blaghag.com/2011/05/hey-dan-savage-did-you-turn-your.html) and resulted in a very entertaining follow-up podcast with Jen McCreight, author of the blog.  

The thing is, individual anatomy varies quite considerably, not just in appearance but also in sensitivity. Female sexuality also varies a lot, some women climaxing from clitoral stimulation, some from vaginal and some from anal. Some from any and all of the above. There are also women who cannot climax. There is no one true way to enjoy sexuality, it will be different for everyone. I feel the focus on the g-spot skips the vast majority of female sexuality and enjoyment of intimate relationships. If you or your female partner has a region on the front wall of her vagina (or anywhere else) that results in mind blowing orgasms and ejaculation, great. if not, still great, because it is whatever you desire and enjoy most about sex and your body that matters, not what others tell you is the be all and end all of sexual experience. There are several different types of orgasm (http://sexuality.about.com/od/orgasms/a/types_of_orgasm_2.htm), so just go ahead and enjoy what you will in the manner that best suits you.
