My SO has never had a vaginal orgasm and, believe me, I've spent a lot of time with oral and sexual foreplay. A former ATF sometimes could be in double digits by the time we were finished. Two ends of the spectrum.

And, no, they weren't faked. Unless lots of squirting can be faked easily, too.

...it must be said again, every single woman is different. i have never had an orgasm from direct clitoral stimulation...in fact i find merely having my clitoris touched or fussed with in any way to be quite irritating and sometimes painful. and for reasons both psychological and physical, i loathe receiving oral sex. i repeat, LOATHE.

but good old-fashioned PIV intercourse i absolutely love, and though i orgasm rarely (just no desire to frankly), that is the only way for it to happen. orgasm or no, i don't care. but happily thrust and pound away, leave my poor little clit alone, and i'm a very happy girl.

My wife is one of those rare cases who almost always orgasms vaginally.  I know where her spot is so it's easy for me to hit over and over again.  I have been able to make her cum from clitoral stimulation, but she generally gets off on the penetration.

With woman I've had experiences with it would seem that the mental aspect of sex is just as important as the physical when it comes to orgasms.  For instance, a woman who holds a grudge or feels neglected in other parts of her life by her SO may have a very hard time having an orgasm if at all.  For some women, that exact circumstance can also be seen as a turn on in a strange twisted way (see: grudge fuck).  Reading your partner is one of the most important things.  If she seems unresponsive try being tender and affectionate rather than mechanically pounding the crap out of her.  It increases the hormones that are responsible for that "loving feeling" which will help pique her sexual side.

Most Women are great actors when it comes to faking orgasms. The only way, I know of, to tell if her vaginal orgasm is real or fake is if she has strong pulsating vaginal contractions.

Out of around twenty or so women I've had somewhat regular sex with in the past ten years or so, Only two seem to have had vaginal orgasms (If indeed they were real and not fakes, which is a possibility.) versus most of the others who came from clitoral stimulation (almost always as a result of cunilingus.)

In fact, I've know three gals who come from anal penetration.

What does this tell us?
