Walked in on a guy roommate naked in the middle of night?

I am a girl and I sleep naked. I am in a science camp this summer and we have known each other for 7 weeks. Yesterday I woke up in the middle of night to use the restroom and was too lazy to put some clothe on. Then I walked in on a guy, who is also in the camp and lives on the same floor, in the hallway when I was completely naked (He had his pj on). He turned his head away and I felt so awkward and went back to my room... Is it inappropriate for me to walked around naked as a girl? I have to see him for another week. How should I deal with this? I guess we are both shy and do not know each other quite well. Help!
