71 yr old female always with a hard clitoris and wanting to orgasm

I am a 71 year old woman, I have always loved sex.I am not married, my problem is I need to masturbate constantly, I usually masturabate up to 6 times a day.I have a very active and hard clitoris, and still have no problem with moisture. My nipples are very large and hard, almost like I am breast feeding. I do not know how to handle it, it is my first activity of the day and my last at night. My hands do it all.It is getting worse as I get older. I wear most men of my age out and they stay away. They love it the first few times but they get worn out as I can go on and on. This is not funny because I want it so much all the time. I orgasm without even touching my body, more now than when I was a very young girl. Help me!!
