Sounds like you are doing well for only a week in, don't get discouraged though, it does get better :)
I am about 4 months of Straight shaving in now and I thought I'd never get past those first few weeks, I was bleeding and couldn't get a close shave to save my butt, one day it all just clicked and I got a presentable shave and it gradually got better an I gained confidence with the straight, still don't have the guts to try scything on the neck but eventually.
PS, even 4 months in, I still have to touch up my neck with the DE, just haven't got the trick of getting close with the str8 there yet....but I'm in no rush, Straight shaving is all about the journey my friend not the destination :) Just relax, slow down and enjoy the ride :)
