I am Kind of worried, he's a nude. Help?

So I met this guy. We went on a few dates. We really liked each other. He never took me ti his house,we never went to mine I thought it was a sensitivity thing. eventually he asked me to be his girl friend. I said yes. He took me to his house and his room mate was naked! like all the way! I looked away. He went to his room and can out just in under wear and said " surprise! I'm a nude!" I was shocked. we went into his room and "did it" in the morning I left. What do I do. Cause I really like him and He really likes me. Help!
