Is it normal to masturbate several times a week when you are old?

I'll be 82 on November 15, and I still have a strong libido. Yesterday while my wife of 57 years was getting her hair done at the salon, I called our black doorman to give him a heads-up and to have him call me at 10:45 which he did. We talked dirty to one another and after I came, we hung up. But then at 11:00 I called Judy in Naples and told her I was jerking off and we talked more dirty fantasies. And again, I had a wonderful ejaculation. Then we hung up. I wonder if I'm a sex addict. I've had over 130 man and women hundreds of times over my lifetime and still look forward to more! Do other elderly men and women still have sex like I do? Yes, I'll tell my wife later and we'll probably do it by intercourse or masturbation which she also enjoys. Jim
