Soldato
this thread is far too long to read it all so this may have been suggested already. what i do is i use a cheap electronic shaver (something like this) which i then can use to shave to a fairly low length every couple of days. i never have to use water or ever suffer from any itchyness afterwards as it doesn't cut too close to the skin. obviously it doesn't leave a perfect clean look and probably isn't great for people with quicker growing hair, but i'm only 21 and it's perfect for me. had one a year now and never had to spend any more money on it
