It gets better. Finally, I remembered to ask the nurse something today. I was almost 70 before I knew what caused the "Big O." I thought it was contractions of the uterus. No, it is not! It is the contractions of the pelvic floor. Since I had my hysterectomy, I have been told the pelvic floor is weakened with the removal of all female organs--ovaries, fallopian tubes, and uterus.
Since incontinence was/is a problem and I really did not want anything sagging inside, I surmised that maybe "O" might keep the muscle that is the pelvic floor strong. The nurse smiled a huge smile when I asked if "O" would keep the pelvic floor, a muscle, strong. she said it's the best kegel exercise ever.
Since the "O" can be had several ways, I leave it up to you to decide how you want to achieve it.
Yes, this is embarrassing for me. But. we need to do this exercise...lol. Knowledge is power.
Oh yes, I asked if the tibial nerve stimulation helped men, too. Nurse said "yes".
Are you scandalized by the frankness of this post? Sorry. I just know this will help someone.
