One possible cause of ED is using too firm a grip while masturbating. Sex advice columnist Dan Savage says the tough love of “soft” love is the only solution: “No more gripping your dick like that, HARD. From now on, whenever you masturbate, you’re going to jerk it with a light touch and few drops of lube. And if you can’t come using that lighter touch and a few drops of lube, then you don’t come. At least for now.”
