Answers to your questions, MPBallin,

1) It depends entirely on the circumstances and on the woman in question. Treating "women" as a monolithic entity is a big mistake. People have all sorts of different motivations for sex. Some women have sex for benefits and could care less about orgasming. Others go into the sex act fully expecting to orgasm and get angry or disappointed if they don't.

2) Please understand that about two-thirds of all women out there do not orgasm exclusively through vaginal penetration. The vast majority of women need clitoral stimulation. Now this could mean pure cunnilingus or a combination of oral/hand/penile stimulation of the clitoris. About one-third of all women are capable of vaginal orgasms simply because their clitoral systems (the clitoris is NOT just one little button) are connected by proximity and nerve endings to the vagina. CAVEAT; ALL WOMEN ARE DIFFERENT - THERE ISN'T ONE WOMAN EXACTLY LIKE THE OTHER. IT'S A FALLACY TO THINK THAT ONE SIZE FITS ALL WITH WOMEN. Mysteriously, someone who reportedly climaxed exclusively through clitoral stimulation could have a vaginal orgasm with one guy and not with another. THERE ARE NO 100% NORMS OR RULES.

3) NOTHING IS STANDARD. IF THERE'S ONE THING YOU TAKE AWAY FROM THIS THREAD IT IS THAT NOTHING - AND I MEAN NOTHING - IS "ALWAYS" WITH WOMEN. Your friend is right in that two orgasms are not "standard" - note that a minority of women NEVER climax and seem to be OK with that. Now his perception that "girls he's been with just seem happy to have dick in them" may seem accurate to him in the moment, but if you ask some of those women, their response may be entirely different.

The best approach is to find out what each and every woman wants and not apply any rules or standards to them beforehand. Guys who think of "women" as some sort of monolithic entity often lose out.

There are two women whom I have been seeing for quite a number of years who need to take antidepressants which prevent them from experiencing orgasms.  Yet both seem to always be very anxious to engage in vaginal and with one, anal intercourse and claim to enjoy the feeling very much.

It seems to work for them, and it certainly works for me.

Moral of the story is that there is more to sex than orgasm.

I have had many experiences with civvy girls who didn't have orgasms..I had one GF for a few years who never had a orgasm with me and she said she had never had one with anyone else..I came home one night with a vibrator and did DATY with her while using the vibrator for over twenty minutes  and she had her first one ever ..After that she had many but certainly not every time unless i used the vibrator daty technique..
The thing I like about providers over civvies is civvies usually take at least 17 minutes to orgasm during DATY where a provider is trained how to orgasm and she will O in a couple minutes or much less depending on the length of the appointment..
I don't know any factual statistics but from my experience only 70% or less of civvies orgasm with me, and 100% of providers have multiples..
I don't watch porn but I love good actresses in the movies and the bedroom.

LG, as always, hits it right on the head.  My wife is one of the third of women who climax from vaginal sex.  I do have a technique during mish where my pelvis grinds and slaps on her clit as I'm penetrating which usually sets off an orgasm for her.  Sometimes I even turn up the heat and one of those Tongue Joys on the base of my cock so it hits and vibrates her clit every time I push all the way in.  She loves it because she gets the stimulation from those full strokes that hit her G-spot and the vibes on her clitoris.

If you don't have such a toy you can always try massaging her clit with your finger or have her use a vibrator on herself while your having sex.  I personally find it hot when my wife masturbates during sex, although she rarely has to do that in order to climax.

Like LG says, every woman is different.  A smaller few just don't know their body well enough to help trigger the orgasm by positioning herself to achieve maximum stimulation.  For some it's a mental thing - they have to be really into you or feel certain emotions in order to achieve orgasm.
