Whoa there cowboy, before you contradict The Journal of the Society for Behavioral Neuroendocrinology on the female orgasm, I would start with some third sexual education and understand basic female anatomy.
Here’s another article I wrote that might help: https://medium.com/sexography/secrets-about-the-female-body-every-man-should-know-2210e757403d
My research on the urethra/clitoris connections was peer review:
You are confusing the glans clitoris (the visible fleshy tip) with the whole enchilada. The clitoris is as big as your penis (maybe) and branches out like a wishbone wrapping around the vaginal opening. I really do my best to educate men on this subject but you first should talk to some actual women. Plenty will tell you that they have some pretty fierce orgasms from penetration.
