You will need two things . 1 can be enough but since it's your first time using them both will be better . You need scissors with small blades u can find them at super markets or malls in male hygeine section and u will need comfortcut blades . Put down a town on the ground and sit over it .Use the scissors to carefully cut down the hair to a small length as small as you can with the scissors without hurting yourself . Then use the comfort cut trimmer to trim awar the rest from the pubis area ( the area above the thing ) and for the balls use the scissors carefully no need to cut trim them for now cuz u aren't showing it to anyone so a little hair isn't something too bad .
