Hey modest, welcome to the SBG site!. Good to have you with us. I'm with Cam on this, get yourself a HeadBlade!, ditch that piece o' crap disposable.
(Pick up some Headslick shave cream too!)
Read the instructions that come with it, check out the posts in our headshaving section. Follow to a T. If you do, I can guarantee a smooth, slick shave with no cuts or nicks.
