It is not true that “A huge portion of the clitoris is actually tucked away inside a woman’s body despite stimulation of the clitoris being critical for orgasm. Stimulation for a penis is very direct; it's often far less direct for the clitoris.“
The orgasm-triggering nerve-ending organs of both penis and clitoris are external, in the glans. The parts of the clitoris that are tucked away inside the body — the crura (legs) have no nerve endings. Like the penile crura, they simply anchor the sex organ to the pelvic bones for stability. Therefore, the direct stimulation that induces orgasm is exactly as easy for women as for men.
By repeating this erroneous narrative about the “inner clitoris,” you are perpetuating the myth that women can be stimulated to orgasm by penile thrusting — the so-called “vaginal orgasm” that men demand and women cannot perform. Anatomy and neurology — and experience — make it clear that, to reach orgasm, women require stimulation of the external clitoral glans, as protected by the hood and labia. The only effective “indirect” clitoral stimulation is stimulation of the tissues around the glans, which, with twice the number of nerve endings as the penile glans, is extremely sensitive.
Just as you see with your eyes by receiving external stimuli through the optic nerve receptor nerve-ending organs, you experience the orgasmic nerve reflex by receiving external stimuli through the pudendal nerve receptor nerve-ending organs. You cannot see by “stimulation” (e.g., by pressure) of the optic nerve portion that extends to the brain.
The new “tip of the iceberg” analogy that grew out of recent MRI imaging of the genital organs (actually fully mapped in the 1830’s) is useful only in reviving awareness of the fact that the clitoris has the same volume of erectile-tissue capacity, and therefore the same potential for orgasmic intensity, as the penis, since orgasmic intensity and satisfaction correlate with the level of vasocongestive release through pelvic-tissue contractions set off by the orgasmic reflex.
You are a PhD; you should be more careful about echoing what you read in all the other blogs and books without conducting your own critical analysis of the literature. Men will take what you say and expect women to reach orgasm from penile thrusting. And women will feel that they are failures because they can’t. That kind of orgasm has never been verified to exist. While arousal can be caused by all sorts of stimuli, including intercourse, imagination, nipples, earlobes, red shoes, etc., and the contractions that constitute the orgasmic release may be felt in the vagina and other pelvic organs and tidies, those orgasms are triggered by the nerves in the clitoral glans, which is easily accessible for manual, oral, or other stimulation — not by intercourse.
