Warning, perhaps a little graphic. (good thing I’m writing this, I’d be blushing too much to discuss this in mixed company in person!!).
According to noty only the sex manuals I’ve read, but plain old personal experience and discussion with many other females, the old Freudian theory of an “immature” clitoral orgasm vs. a “mature” vaginal orgasm is a bunch of Hoooey.
The clitoris is how a woman has an orgasm. Aside from the “G” spot (which in sexual manuals and documents I’ve read hasn’t been proven beyond the shadow of a doubt to actually exist). That’s how a woman has an orgasm. Period.
If a man is able to effectively stimulate the outside of the vagina in the vicinity of the clitoris, then yes, it’s possible for her to have an orgasm via penetration.
Generally the Kama Sutra position (the name of which I’ve forgotten) where the couple “rock” while performing penetrative sex is the ticket for orgasms while having vaginal sex.
Plain old “in/out” where little to no contact is made with the clitoris just doesn’t do it.
According to The Kinsey Report. Barbara DeAngelis “How to Make Love All the Time” and the Johnson’s report (I know, Old, but still applicable), only about 25% of the women are able to have an orgasm through vaginal sex alone.
Most need direct clitoral stimulation. I can’t speak for all women, but for me, the answer to your question is somewhat of a “yes”. But it doesn’t have to be just oral.
My boyfriend has this trick where he uses the soft tip of his penis to stimulate me on the outside every three or four strokes. He uses a lot of soft strokes with his hands during most of the sex act. Without that, just penetration wouldn’t do it.
Sorry for the extreme graphic explanation, but I hope that helps.
Last thought.
The bottom line is that if a man cares enough to find out and DO these things and that he truly enjoys sex if she’s enjoying it, and not just to “get his rocks” off. He’s a “good lover” even if he’s in the beginning stages and hasn’t quite gotten technically very skilled yet. (I believe that SHE has to “help” and communicate to him what’s good etc, she can’t just lay there and file her nails while he figures it out).
It’s all in the attitude and his “want to”. IMnsHO, even if a man is technically good, but he’s all removed and distant (and many of us can tell), and is pretty much just in it for “scratching the itch”. That’s a “bad” lover to a lot of us.
