I understand the sperm and semenial fluids are seperate and mixed in the urethra before ejaculation. but I don’t get the process over time. The epididymis stores semen.. but does it not release them into the vas deferens until the actual point of ejaculation or are the vas deferens full the entire time the male is erect? Also, what happens if you almost cum and stop? does anything work backwards? can the semenial fluids from the prostate and seminal vesicle work there way back into the vas deferens into the testies themselves?
