"New research suggests that a simple measurement -- a "rule of thumb" -- might be the key to the pleasures of sexual intercourse. About 75 percent of all women never reach orgasm from intercourse alone -- that is without the extra help of sex toys, hands or tongue. And 10 to 15 percent never climax under any circumstances"

75% can't get off P to V. Wow... pretty sure I'd be an angry twat-wagon too.

"He wants to determine if a woman's ability to have an orgasm with penile stimulation alone depends on how far her clitoris lies from her vagina -- the so-called "C-V distance."

The article goes on to say the optimal C-V is about an inch.

Makes some sense I think... basically if your junk does not line up properly with her shame-cave to provide clitoral stimulation, it's not gonna happen.

Now throw in years of hyper-stimulating vibrators, over-sized dildos and other toys & we have a perfect storm of orgasmically challenged women.

""What is startling and surprising to me is that both men and women buy into the same sort of cultural model," he said. "If he is a good lover, he can bring me to orgasm with his penis alone. And a man buys into that and doesn't offer any kind of stimulation. And because he's not any good, she won't say anything because it's emasculating."

People actually believe that an orgasm is something another person gives to you. Just like the proverbial "He makes me (happy/sad/angry/whatever)" nonsense. All of this is blame avoiding behaviour and most of us have been on the receiving end.

I see this as a similar thing as getting a child to eat their vegetables. I basically have to "trick" junior into eating their veggies. I didn't eat them and regurgitate masticated veggies into their mouths, I just deceived them into doing it themselves. Same with the "tingles"... I'm not really doing much... just tricking women into doing it for themselves.
