I "learned" how to shave with the straight by watching youtube vids, and while helpful, the shavers move pretty fast- much faster than beginners should even attempt.

I was in a hurry to go to work, and it was the third day I'd shaved with the straight. The first two days went without incident, and I was thinking this is pretty easy. Shaving under my nose, I was too quick in moving the razor, and basically stabbed myself with the sharp corner. Didn't stop bleeding for hours, even with butterfly closures. Man, was my wife pissed.

Now I switch to my DE when I'm in a hurry, or in the middle of a shave and I'm just am not feeling confident in my technique, or the straight razor pulls a bit on my neck.
