ahhh congrats on giving straights a go. my first 6-7 shaves with a straight were disappointing and i felt somewhat downhearted. Its a big learning curve, stropping and shaving. as you dont know which bit your doing wrong. is it the stropping, have i blunted the blade, is my angle wrong. etc etc
stick with it, learn areas of your face (were some bits actually decently shaved?) tugging is bad - either you need to improve prep, angle or blade
concentrate on certain areas at a time - they recommend learning to get good shaves on your cheeks first, but its all down to what you feel at the time. best of luck
