Hi and Welcome with a big "W".
I recently started str8 shaving and have cut myself a few times. Actually, probably every 1 out of 2 shaves :) But I'm definitely getting better and the cuts are not bad. THe styptic pencil is about $2 and stops bleeding.
The cuts themselves don't hurt, the razor is too sharp to make jagged and painful cuts. Because of the sharpness, wounds also heal a lot faster.
hope it helps you on the road to becoming a str8 shaver
