Too steep of an angle(especially when you complain about the shave being too loud, do you mean like velcro getting pulled apart?) and too much pressure are the usual culprits for beginners, atleast it was for me. I kept thinking I was using proper pressure but I realized it was getting less and less every shave. The angle is hard to get right for a while, until you get used to the different grips needed to complete a shave. You should never have to go over 30 degrees and the correct pressure will be practically none, just take the whiskers. Your face will also take a while to get used to being shaved by a straight, it took my face a good 2 weeks and my neck a couple more than that until the severe irritation ended. It will take some practice before things start to come together, but I guarantee that the razor you got from SRD is more than sharp enough unless you have messed up the edge on your strop.

Edit: And give your face time to heal before trying again, I went 2 to three days between shaves when I first started.
