I have just read an interesting, although I think outdated book called "The Hite Report" The grand theme of the book seems to be fact that most women do not orgasm from penetration alone, and if they do it is because the clitoris tip* is stimulated during the act. Now I tend to disagree with this statement as it does not correlate with my own reality and experiences. The 2 most powerful erogenous zones are the G-Spot and the AFE Zone/ Deep Spot. They also usually cause the most intense orgasms. Both of them are especially well stimulated during penetration. However, those orgasms are much harder to come by as they a.) require high levels of arousal, especially to 'activate' the G-Spot and b.) require the right 'tools' to hit the right places, e.g a long or girthy penis. So, assuming we have a competent lover in the first place, can the lack of 'penetration orgasms' be attributed to insufficient penis length/girth? --- * clitoris tip is the visible outside area of the clitoris which seems to be topic of the Hite Report, and not the 'hidden' area of the clitoris that is inside the body.
