Don't be afraid of the razor. It's a tool and like any tool, it deserves your respect, not your fear. In the next few days, you will nick yourself. There's no doubt about that. But a nick is only a nick, you'll only feel a short, split-second little sting, it will cure without hurting in a few days.
Don't curse yourself for being afraid. We all were afraid when we started. It's the first thing you need to let go.

I don't know anything about the tosuke, but if you're sure that it is shaveready and it is not cutting whiskers, the cause must be that you don't use the right angle to put it against your face. Minimal pressure is a good thing. Lay the blade flat on your cheek, right underneath the side-burn and start stroking downward, while increasing the angle until the razor starts to cut whiskers. The shallowest angle that works is good for learning. Later you'll learn to experiment with the angle a bit to improve closeness of the shave.
You'll get the hang of it pretty soon. I'm sure of it.

Have fun,

Bart.
