I don't know where to start!

Okay so I'm a 52yo Australian police officer with a lifelong history of compulsive masturbation, not just to porn. I masturbate three of four times a day, a couple of times at work, and its got to stop. I don't want to ruin my life! I have tried to stop, and once managed six weeks without masturbating, but then I went to the bathroom and found myself wanking to nothing at all and came like a fountain, on and on, for what seemed like forever. And it felt sooooooo good. I have started masturbating in public places, on trains, buses, anywhere. I masturbate after I've had sex with my wife. I masturbate after I've masturbated. I masturbate to any and all kinds of porn, and even when I am totally sexually exhausted my dick still gets hard over nothing. I don't wear underwear anymore because I spend so much time erect that it is uncomfortable; but the result is that I see people staring at my semi-erect penis, and that makes me even more aroused. It doesn't help that I am much larger than average, but maybe that's why I was so focused on it from such a young age. I feel like this is a death-spiral I'm trapped in, and I can't escape. I feel like there is so much of my life lost to mastubation (1-2hrs per day) that I could have spent doing something else. I feel like a hollow man. I'd like to stop, but don't know where to begin. This isn't as simple as cold showers and thinking of England. I've even thought of seeking some form of chemical castration, but that would make me into somebody I don't recognise. If anyone is in the same chronic circumstances, please help me. Please tell me what I can do -- show me the first realistic, non-bullshit thing I can do to stop.

 

Two cents worth is better than zero. Thank you. I get that this is subjective, and that my triggers are probably negative things in my life. But I don't just masturbate when I'm bored, lonely, stressed, etc. I also masturbate when I'm happy, energised, confident, etc. I haven't watched porn now in two days, but only because my wife spontaneously performed oral on me last night after a very physical day, and she left me fully drained and totally exhausted. But because I haven't ejaculated since then, ie. today, my penis is swollen to the point that its almos sticking out of my shorts, and I'm seriously struggling not to put my hands on it. I don't need porn, is my point, porn just makes jerking off easier and quicker. I don't need porn to masturbate, I'd masturbate almost as much if porn did not exist. For me porn is useful when I want to cum so that I can focus and eliminate the distratction that arousal causes because of the sensation of having a semi hanging down my leg. I'm explaining this badly, but I can't go outside on days like this, I just can't hide it. I feel like a deviate and -- reminder -- I'm a cop, so that doesn't work. So what I still need is ***practical*** advice. What is something that I can do to stop being aware of my penis all the time. I can't make it smaller, it's just there, always in the way, always wanting attention. Its stupid because if you believe PORN then I should be happy. Doesn't everyone want an eleven inch dick? I'd it away in a second.
