Don't you think that the reason that the so-called G spot stimulation is so effective for sexually stimulating a woman is that it is actually stimulating the clitoris at that point where the clitoris forks not the anterior vaginal wall? From my limited physiological understanding it seems to me that all female sexual pleasure is a result of clitoral stimulation and that doesn't necessarily mean the glans of the clitoris. For example, one of my girlfriends could only come from penetration whether penile or digital. That means that in her case that the shaft of the clitoris was being stimulated through the vaginal walls and that was what got her off.

Finally, I do not understand this obsession with 'squirting'. I have had sex with nearly 100 women and none of them have ever done this. The only experience I have of it is from Pornhub. Why this seems to have become a common pornographic trope is beyond me. It is not a common or necessarily desirable response. A normal orgasm is more than sufficient.
