I Would Like To Remove My Desire To Masturbate Several

I would like to remove my desire to masturbate several times a day. I'm married y to my wife of 34 years, I'm 60 years old, in excellent health according to my Dr. I am considering castration to remove the drive. My wife and I don't have set any more because neither of us wants it. I have ED anyway. Can I take a hormone blocker, which one would you suggest?
My Bride and I are still romantic and emotionally love each other, in just sick of the desire to masturbate constantlt.
