A week isn't long enough. I always hated boxers and wore briefs for many years until middle age. When I decided to give boxers a second chance, it took 3 weeks minimum to get used to them. Then I found that the loose fit was really comfortable and understood why some guys like boxers. A month after the swtich, I tried on my former favorite daily wear briefs and didn't like the snug feeling. For 5 years, I never wore anything but boxers. Since last summer, I've been switching it up now and then. Sometimes I'll wear briefs to work. It feels really different than wearing boxers, yet it's fun for a change.
