I too sympathise, Nishy. The area you're talking about is always an area to be careful with in my own case. (That and either side of the adams apple...where 'swallowing' and 'holding' for a second or two helps, as well as dragging the skin with two or three fingers to one side (i.e. off the top of the adams apple and over to the side).... and then cautiously running the razor over the stretched area in the appropriate direction(s). But you knew that already.
BUT, for me, the only sure way to do it with a guarantee of no blood and a pretty close result...is to use a Gillette Sensor. In any direction, willy nilly, with gay abandon! Never any nicks - ever! The very same Gillette Sensor that I seemed to have managed with for 53 years (how did I manage without using a DE razor for all that time? But somehow I seemed to get by!)
