Abstained for 20 Years...Now at 70 I Can't Stop Masturbating

Dear Dr. Betty,
I am a 70 year old woman and have masturbated on and off since I was a child but have abstained for the past 20+ years until I can bear it no longer. I have started again and my sex drive is tremendous! I just can't get enough, using dildos, vibrators, by hand and pillow humping (which was the first method I used as a child).
