As I have recently found out, there is usually a *big* difference between what a new guy (like you or me) thinks is sharp, and what truly *is* sharp. I would find a honemeister there in Australia to sharpen that blade for you. Then all you really need is stuff to *maintain* the edge, instead of actually sharpening it. There are always multiple solutions to every situation, but here's a pretty good one for maintaining a sharp blade: get a four sided paddle strop. Paste it with 3.0, 1.0, and .75 diamond pastes, then CrOx on the fourth side. When stropping no longer provides you with a comfortably sharp edge, try a few laps on the CrOx, then strop it again. If that doesn't work, go to the .75 for a few laps, then strop it again. You get the idea. The nice thing about a pasted paddle strop is it's easier to use than a stone, and you can still get very good results with it. The hardest thing about a pasted paddle strop is making sure you don't apply too much paste. Other than that, it's easy enough for a ham fisted guy like me to use.

If you are using correct technique, using a straight WTG should be every bit as comfortable and irritation free as any other non-straight razor. If it's not, you probably haven't hit sharp yet.
