I think there's two possible explanations for irritation: 1) technique/shaving with too much pressure; or 2) razors aren't properly sharp, causing you to shave with pressure to cut hairs.
When I started, I needed a day between shaves so my face could "relax," due to irritation. Now when I walk away from the mirror my face feels relaxed and pampered. I've shaved two times in a day many times, each time walking away with the same feeling.
