Very itchy bumps all over genitals and abdomen, is it razor burn?

Could be: I am guessing that you just shaved there past day or so? Usually a soothing cream (vanicream aveeno (oatmeal) aquaphot) with no fragrance should help....It should heal itself ... But if very red and tender see your dr. To be sure you don't need a prescription cream. An antihistamine might also help .Allegra etc just read the labels. Good luck.
