I am a sort-of newbie, but have had the cold head problem since forever. I don’t recall ever having one of those nice fat muscular-looking dicks when flaccid. Sometimes it’s even pale and wrinkly. Not only that, but even my scrotum gets cool. I think it has to be poor circulation, which is true over much of my body — I very easily get cold toes, for example. I’ve been taking gincko and saw palmetto for years, and if they’ve helped, they certainly haven’t cured it. I recently started massaging scrotum, BTB, and perineum, and am getting a bunch of kegels in every day, but started too recently to see what effect thay might have.
