Lot's of good advice here.
You have to accept that there will be a fear factor and learning curve, but there was already a fear factor and learning curve when you started DE shaving, wasn't there?
Don't expect the first 100 or so shaves to be up to the same level as a good DE shave.
It took me about 60 straight shaves until my wife couldn't tell the difference any longer.
I never hurt my face seriously with a straight razor (though I did cut my finger once early on when wiping off the oil), but the first shaves did leave some weepers and minor cuts on my face. (Think: wrestling with a cat.) Perseverance is the key.
When I switched from DE's to straights, I put DE razors aside and shaved only with straights, except for the last ATG pass that I performed with my open comb DE for the first 20 or so shaves.
Shaving every day with a straight helps, but you need to plan for more time.
A three pass shave with a DE razor takes me 10-12 minutes, a three pass shave with a straight razor that is already stropped takes about twice that much.
Lastly, DE shaving is a routine that is preferable to the chore of a system razor shave; but shaving with a straight is essentially a hobby that requires time to perform and time to become proficient in.
FWIW; only much later did I buy a Feather AC DX and Dovo Shavette, since I don't believe in either razor as a training aid for straight shaves; but opinions on this matter clearly differ.
