First off, I suggest you use more credible sources. Here is an article from the Journal of Sexual Medicine examining the G-spot using magnetic resonance imaging: https://www.jsm.jsexmed.org/article/S1743-6095(15)32498-X/fulltext

You can see the clitoris network in the imaging! So stop. Please. This flat earth denial crap is not helping. Just because you can't see 90 % of the clitoris does not mean it does not exist.

Better yet, how do you think blood would flow to the clitoris without a venous network?
