Don't answer this, but do you keep it trimmed? I found that trimming very short relieved my itching. I can't shave smooth or wax because horrible ingrown hairs every single time, but that may work too. And I do think mine became more sparse, and more gray. Also, cotton panties. I tend to get itchy anyway in synthetic fibers, pants, shirts, everything. I can hardly tolerate synthetic fiber undies at all anymore. All part of normal aging or low hormones?
