 [ Symptoms ] i have been diagnosed with anemia [ Disease ] hi first thought could be from masturbating if you use a tight grip and no oil try just masturbating with a feather light grip and some baby oil or this could be from washing powder either your mother you or your wife uses your getting a reaction to it it may have been changed at the time you got the rash if so just ask for your under wear to have extra rinses or ask for them to be washed in some natural soap just see how this goes good luck
