shaving is too fucking itchy for me, I used to have to be clean shaven for jobs and it drove me batshit - just one more sensory annoyance. These days I just use the trimmer or a pair of sharp scissors to keep my beard/tash from becoming too Islamic.
Same here, exactly - batshit!
I don't bother with scissors, though. I actually have a decent model electric trimmer with attachments for various lengths of trim and the bare blade itself adjusts from "Leave an eighth inch" to " Remove a layer of skin or two" so I can get as close as I want along the edges. It is much easier to get straight cuts than with scissors with my weird red beard.
