Now that you know the coronal ridge hook is there, you may be wondering,

Certainly not to create discomfort and/or pain
for the woman, during intercourse and/or after,
like the circumcised penis can.

Truth is, nature designed the penis head to flare out at the corona for a reason, and the presence of the coronal ridge hook on the natural penis head is proof  that the foreskin's primary purpose is sexual.

For the woman, the bunching and unbunching of the foreskin during intercourse creates sexual excitement by alternately applying, and then releasing, pressure against the vaginal walls.

In addition, and most important, you will learn in Reason #7 that the foreskin's movements up and down the penis and its rhythmic bunching against the coronal hook work to regulate the penis's thrusting rhythm at the "ideal" tempo that creates maximum pleasure for the woman and builds her
to orgasm.

In other words: The foreskin and the hook work rhythmically as a team to enhance sexual pleasure and orgasmic build-up for both the woman and man during intercourse.

In the future, when someone tries to tell you that the foreskin is useless, redundant skin, you challenge their thinking by asking, "Well, why then does the penis head typically flare out like a hook?
What is the hook's purpose?"

ANSWER: The hook captures the foreskin...
