That is very interesting. Are you saying that you can go beyond the cervix and into the unteris? I will have to try and perfect the art of cervix rubbing. Thank you fellas for opening my eyes.
No you definitely cannot go IN the cervix/into the uterus. BUT the cervix can pull back when she is very aroused/stimulated and depending on her hormones etc, and the penis can slide under/over it and actually rub against the outside wall of the uterus, which can be pleasurable. The vagina doesnt simply “end” at the cervix.
