I would probably attribute your difficulties to the simple fact that you are still learning how to shave with a straight razor. I'm in the same situation as you and I am still figuring out the best ways to shave certain "trouble areas". Do the hot towel over lathered face a couple times, it works a dream for me. Strop your blade really well, 50 strokes or more, try adding glycerin to the lather etc. All sorts of stuff to try.
