I can't argue that FE don't exist, I was lucky enough to be there for one, more over I caused it so Yeaaay for me. The real reason such things don't get researched is that people are prudish in areas of research. Most Academic research is done by Graduate students or post-doctoral students, under the guidance of their Advisor. Strangly few Advisors out there are going to say, "hey, Lets study the G-Spot", there is no Nobel prize for medicine going to be awarded for it. (personally I think it should get at least honorable mention, but it won't). I guess my real point, assuming I have one, is that research facilities are set up in a higherarchy, and if you go up the higherarchy far enough you will find a prude. Hell, I am prudish when not semi anonymous thanks to this forum.
Lastly, Thank you Lixy for posting the pic, please don't appologize.
