Did some quick research on the membrane between a chicks vag & anus. It’s called the perinium and if you’re DP-ing a bitch, it’s the only thing between you and a gay bonobo sword fighting exercise.
Men also have a perineum
It is important to know about it for breathing exercises in qigong and yoga
@marlathetourist
I have not studied them extensively although I am probably more familiar with them than most non Asian people
I am familiar with the perineum because it is an anatomical location name in western medicine that over laps with instructions one might have in modern internal martial arts books or classes
The meridians or nadi maps in Indian & Chinese tradition generally do not overlap with the circulatory nor nervous system according to wikipedia last time I read some article
Is it this book with that name by this author I found on worldcat worldwide library catalog at this link?
@shortstories You’ve studied the meridians then? Some Yogi wrote a book called the Science of Breath.
