>>447233No, it's more likely you've just damaged your penis's nerve endings. I'd wager that not only do you feel less pain from the frequent fapping, but it also probably feels less pleasurable due to severely reduced sensitivity. Even people who masturbate less than half as much as you report lowered sensitivity, so that's more than likely what is going on. You've simply abused your poor penis so much that you no longer feel it.
But as to detrimental effects on life expectancy, there is none that I know of arising from excessive masturbation. Generally speaking the only part of your body you're harming is your genitals, and you can live without them (though apparently not in your case). I know less about brain chemistry though, so consider following up on other anon's claims about addiction.
