There's a limit to how close you can get. I also find that shaving after a hot shower decreases pain and irritation. I use a warm wet towel if I'm shaving without the shower.
You are supposed to shave with the grain, not against it, which is probably why your skin is irritated. Multi-bladed razors have the extra blades so that you can shave closer to the skin in one stroke.
As for me, I use multi-bladed razors for shaving my neck area in order to create a good neckline for my beard. I also shave my upper cheeks because my beard does not grow very well there. I use an electric beard trimmer to trim the actual beard to a length when I want to keep it short (in the summer), and then for winter I grow it out and use a pair of scissors to shape.
