It's only to be expected really, and no reason to be downcast. Chances are it's a matter of finding the right angle and that's something which just comes with practice. There's an outside possibility that you've blunted the blade somewhat whilst stropping, but it doesn't sound very likely. Probably most people get off to this sort of start, and the thing is to just keep going till things come right, which will happen in due course. If the irritation is too bad for you to face a shave, don't. Skip a day, then have another go: doggedness does it.
